Read each question carefully and answer to the best of your ability. Show all your work for calculations.

1. What is the formula for the volume of a sphere with radius 'r'?

V = πr²h

V = 4/3πr³

V = 2πrh

V = πr²

2. What is the formula for the surface area of a sphere with radius 'r'?

SA = 2πrh

SA = πr²

SA = 4πr²

SA = 1/2bh

3. A sphere is a perfectly round three-dimensional object in which every point on its surface is equidistant from its .

4. The distance from the center of a sphere to any point on its surface is called the .

5. The longest distance through a sphere, passing through its center, is called the .

6. A sphere has a radius of 6 cm. Calculate its volume. Use π ≈ 3.14. (Round your answer to two decimal places).

7. A spherical ball has a diameter of 10 inches. Calculate its surface area. Use π ≈ 3.14. (Round your answer to two decimal places).

8. All cross-sections of a sphere are circles.

True

False

9. A hemisphere is exactly half of a sphere.

True

False

10. If the volume of a sphere is 288π cubic units, what is its radius?

11. A spherical tank has a surface area of 196π square meters. What is the diameter of the tank?
