Question

A cylindrical can has an 8-cm radius and a height of 11 cm. Find its surface area.​

Answer 1

955.168 cm²

Explanation:

The formula to find the surface area of a cylinder is :

Surface area = 2 π r ( r + h )

Here,

r ⇒ radius ⇒ 8 cm

h ⇒ height ⇒ 11 cm

So, Let us solve now.

Surface area = 2 π r ( r + h )

Surface area = 2 × 3.142 × 8 ( 8 + 11 )

Surface area = 50.272 × 19

Surface area = 955.168 cm²
