Answer
$A=2000\pi$ square centimeters
$A\approx 3.14\times 2000= 6280$
$V=20000\pi$ cubic centimeters.
$V\approx 3.14\times 20000=62800$
Work Step by Step
This solid is a cylinder and its volume can be calculated as:
$V=\pi r^2 h$ where r is the radius, and h is the height.
Here:
$V=\pi\times 20^2\times50=20000\pi$ cubic centimeters.
$V\approx 3.14\times 20000=62800$
The surface of a cylinder can be calculated as:
$A=2\pi rh$
Here:
$A=2\pi \times20\times 50=2000\pi$ square centimeters
$A\approx 3.14\times 2000= 6280$
