Find surface area please

Lilit [14]

Answer:

131.88 cm²

Step-by-step 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 =

$\frac{2\pi r^{2}+2\pi rh}{4}$

We know:

r = 6 cm

h = 8 cm

Now substitute the values and solve:

$\frac{2(3.14)(6)^{2} +2(3.14)(6)(8)}{4}$

$\frac{226.08+301.44}{4}$

$\frac{527.52}{4}$

= 131.88 cm²
