Question

Find the surface area of a cylinder with a base diameter of 10 cm and a height of 6 cm. Write your answer in terms of , and be sure to include the correct unit.

Answer 1

To solve for the surface area of a cylinder:

Explanation:

SA=2πrh+2πr^2

diameter = 10 , radius = d/2 = 10/2 = 5cm

height = 6cm

`\begin{gathered} S.A=2\pi rh+2\pi r^2 \\ S.A=2*\pi*6*5+2*\pi*5^2 \\ S.A=60\pi+50\pi \\ S.A=110\pi \end{gathered}`

Therefore the correct answer is 110πcm²
