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.

Answer:

I had 271.36cm^3

Step-by-step explanation:

There are 2 figures in the diagram above a cylinder and a cuboid if I'm right

So volume of Figure = V(cylinder) + V(cuboid)

V(cylinder) =pi x rxr xh

Pi=3.142, radius is 2 (since diameter is 4cm), height is 20cm.

So V(cylinder) =3.142x4x20 = 251.36cm^3

V(cuboid) =lbh =1x1x20 =20cm^3

So V(figure)= 20+251.36

=271.36cm^3
