1. Find the volume of the figure. Use 3.14 for π. Round to the nearest whole number as needed.
2. A student was asked to find the volume of the solid where the inner cylinder is hollow. She incorrectly said the volume is 2,034.72 in.^{3}.
a. Find the volume of the solid. Use 3.14 for π. Round to the nearest whole number as needed.
b. What mistake might the student have made?
A. She did not subtract the volume of the smaller cylinder.
B. She found the surface area instead of the volume.
C. She found the volume of a sphere instead of a cone.
D. She found the volume of a rectangular prism instead of a cylinder.
3. The figure shows a peg used in a board game. Find the amount of plastic needed to create one of these pegs. Use 3.14 for π. Round to the nearest whole number as needed.
4. A satellite consists of a sphere with a radius r = 18 m and six equally spaced cylinders with radii r over 2 and height 20 m extending from the sphere.
a. Find the volume of the satellite. Use 3.14 for π. Round to the nearest whole number as needed.
b. Draw a picture of the satellite.
