Question

base area of solid cylinder is
​

Answer 1

Step-by-step explanation:

Having radius r and altitude (height) h, the surface area of a right circular cylinder, oriented so that its axis is vertical, consists of three parts: the area of the top base: πr. the area of the bottom base: πr. the area of the side: 2πrh.

Answer 2

Answer:

For the rectangular solid, the area of the base, B , is the area of the rectangular base, length × width. For a cylinder, the area of the base, B , is the area of its circular base, πr2 π r 2 . The image below compares how the formula V=Bh V = B h is used for rectangular solids and cylinders.
