Find the surface area and volume of a cylinder with a radius of 4 and a height of 6
(pls explain the answer)

Answers

Answered by Damon
surface area = area of top + area of bottom + area of side

= pi r^2 + pi r^2 + 2 pi r h

= 2 pi (r^2+ r h)

= 2 pi r (r + h) = 2 *pi*4 * 10
= 80 pi

volume = pi r^2 h = pi *14 * 6
= 84 pi
