Answer:
985.31 cm² is the volume of the figure.
Step-by-step explanation:
First, find the volume of the cylinder
[tex]V=\pi r^{2} h[/tex] Use this equation to find the volume of the cylinder
[tex]V=\pi (4)^{2} (20)[/tex] Simplify the exponent and multiply
[tex]V = 320\pi[/tex] Multiply
1005.31 cm² is the volume of the cylinder
Next, find the volume of the rectangle
V = L x W x H Use this equation to find the volume of the rectangle
V = 20 x 1 x 1 Multiply
V = 20 cm² is the volume of the rectangle
Subtract the volume of the rectangle from the volume of the cylinder to find the volume of the figure.
1005.31 cm² - 20 cm² = 985.31 cm² is the volume of the figure.
