Question

Find surface area please

Answer 1

131.88 cm²

Explanation:

The surface area of a cylinder is 2πr² + 2πrh

Since the figure we are dealing here is a quarter of a cylinder, divide the equation by 4.

New equation =

`(2\pi r^(2)+2\pi rh)/(4)`

We know:

r = 6 cm

h = 8 cm

Now substitute the values and solve:

`(2(3.14)(6)^(2) +2(3.14)(6)(8))/(4)`

`(226.08+301.44)/(4)`

`(527.52)/(4)`

= 131.88 cm²
