What is the volume of a cylinder with radius 3 units and height 5 units?
15?
45?
27?
20?
The volume of a cylinder is V = ?r²h. Substituting r = 3 and h = 5 gives V = ?·3²·5 = 45?. You must square the radius before multiplying by the height. Learn more about cylinder volume.
Find the volume of a right circular cone with radius 4 units and height 9 units.
36?
48?
24?
64?
A cone's volume is V = (1/3)?r²h. Plugging in r = 4 and h = 9 gives V = (1/3)·?·16·9 = 48?. Remember to divide by three after computing ?r²h. See cone volume formula.
Calculate the volume of a sphere with radius 6 units.
144?
324?
96?
288?
The formula for a sphere's volume is V = (4/3)?r³. With r = 6, V = (4/3)·?·216 = 288?. You cube the radius and multiply by 4/3?. More on sphere volume.
A cylinder has a diameter of 10 units and a height of 7 units. What is its volume?
175?
125?
87.5?
350?
First convert the diameter to radius: r = 10/2 = 5. Then V = ?r²h = ?·25·7 = 175?. Always halve the diameter before squaring. Cylinder volume details.
A cone has radius 3 units and its volume is 50? cubic units. What is its height?
15
100/3
50/3
25/3
Use V = (1/3)?r²h = (1/3)?·9·h = 3?h. Setting 3?h = 50? gives h = 50/3. You isolate h by dividing both sides by 3?. Cone volume explanation.
What is the volume of a sphere with diameter 10 units?
(500/3)?
500?
(250/3)?
(1000/3)?
The diameter is 10, so r = 5. Then V = (4/3)?·5³ = (4/3)?·125 = (500/3)?. Always convert diameter to radius first. Sphere volume formula.
A solid is formed by placing a hemisphere (radius 4 units) on top of a cylinder of the same radius and height 10 units. What is the total volume?
(608/6)?
608?
(608/3)?
(448/3)?
Cylinder volume: ?·4²·10 = 160?. Hemisphere volume: (1/2)·(4/3)?·4³ = (128/3)?. Sum: 160? + (128/3)? = (480/3 + 128/3)? = (608/3)?. Hemisphere volume and cylinder formulas combine here.
A cylinder of diameter 8 units and height 8 units is perfectly circumscribed by a sphere. What is the difference between the cylinder's volume and the sphere's volume?
32?
256/3?
128/3?
64?
Cylinder: r=4, V = ?·4²·8 = 128?. Sphere: r=4, V = (4/3)?·64 = (256/3)?. Difference: 128? - (256/3)? = (384/3 - 256/3)? = (128/3)?. Sphere volume.
A right circular cylinder of radius 3 units and height 12 units has a cone (same radius and height) removed from its top. What is the remaining volume?
72?
36?
108?
144?
Cylinder volume: ?·3²·12 = 108?. Cone removed: (1/3)?·3²·12 = 36?. Remaining: 108? - 36? = 72?. Cylinder and cone formulas are both used.
A frustum of a right circular cone has top radius 3 units, bottom radius 6 units, and volume 108? cubic units. What is its height?
54/11
18/7
36/5
36/7
Volume formula: V = (1/3)?h(R² + Rr + r²) = 108?. Here R²+Rr+r² = 36+18+9 = 63, so h = (108?·3)/(63?) = 324/63 = 36/7. Frustum volume details.

Study Outcomes

  1. Apply Volume Formulas -

    Use the precise formulas to calculate volumes of cylinders, cones, and spheres confidently during the geometry practice test 2B.

  2. Differentiate Solid Shapes -

    Identify characteristics of cylinders, cones, and spheres to select the correct volume formula in the geometry unit exam part 2 quiz.

  3. Perform Accurate Computations -

    Compute volume problems step-by-step and check your solutions against the geometry unit 2B test answers for instant validation.

  4. Analyze Quiz Feedback -

    Interpret results from the volume of cylinders quiz and overall quiz performance to pinpoint strengths and improvement areas.

  5. Convert Units Effectively -

    Apply unit conversion techniques to ensure all measurements are consistent before calculating volumes in the review questions.

Cheat Sheet

  1. Cylinder Volume Formula -

    Master the formula V = πr²h by recognizing it's simply base area times height, a principle highlighted in Khan Academy's volume of cylinders quiz. Practicing this on a geometry practice test 2b helps you see how radius and height interplay in real problems. A cylinder with r=3 and h=5 gives V=π·9·5 ≈ 45π units³, a classic example from university math labs.

  2. Cone Volume Insight -

    Recall that a cone's volume is V = (1/3)πr²h, a fact you'll often verify while checking geometry unit 2b test answers on official exam archives. Use the mnemonic "three's a crowd" to remember the one-third factor, which distinguishes cones from cylinders (Wolfram MathWorld). If r=4 and h=9, plug in to get V=(1/3)π·16·9 = 48π units³, a frequent cone problem type.

  3. Sphere Volume Recall -

    Learn V = (4/3)πr³ by visualizing a sphere as 1.33 cylinders in volume, a tip featured in NCAA's geometry unit exam part 2 quiz prep guides. For a sphere of radius 6, V≈(4/3)π·216 = 288π units³, an example you'll face in many standardized tests. This formula is validated by sources like MIT OpenCourseWare.

  4. Composite Solids Strategy -

    Break complex shapes into cylinders, cones, and spheres to apply specific formulas - an approach emphasized in AP Calculus resources and your geometry practice test 2b. Calculate individual volumes then add or subtract to find totals; for a half-sphere atop a cylinder, compute each piece separately. This decomposition strategy is key for geometry unit 2b review questions and helps avoid error.

  5. Units & Precision -

    Always convert all measurements to the same unit before computing volume, as stressed in NIST's guidelines and many geometry unit exam part 2 quiz examples. Remember that 1 cm³ = 1 ml, which is handy when problems mix centimeters and milliliters. Keeping precision in mind prevents mistakes when checking your geometry unit 2b test answers.
