Formula for the area of a circle: A = pi x r^2

We are given the diameter in this problem, but we need the radius. To find the radius, we will need to divide the diameter by 2.

8 / 2 = 4

A = pi x 4^2

A = pi x 16

A = 16pi cm^2

Hope this helps!! :)

madreJ [45]

Answer:

The surface area of right prism is 12 feet²  , option D

Step-by-step explanation:

Given as :

The measure of base = 4 ft

The height of base = 0.5 ft

The surface area of right prism = perimeter of base × height + 2 × base

Now ,

Perimeter of base = 4 + 4 = 8 ft

So, The surface area of right prism = 8 × 0.5 + 2 × 4

Or, The surface area of right prism = 4 + 8

∴ , The surface area of right prism = 12 feet²

Hence The surface area of right prism is 12 feet²  . Answer
