Question

Which equation can be used to find the surface area of the cylinder?

A cylinder with a radius of 4 inches and height of 16 inches.

Answer 1

V = pi (4) squared (16)

Explanation:

the formula is pi (r) squared (h)

put the radius, 4 into where the r is in the equation, same with the 16 and h.

There´s your answer

Answer 2

Explanation:

To find the total surface area of a cylinder

We get

S.A=2πr^2+2πrh

S.a=2×3.142×4×4+2×3.142×4×16

S.A=100.544inches sq+401.192inches sq

S.a=502.464inches sq
