Question

What is the area of the top of the water buoy as shown in the figure?

84.78 square in.
37.68 square in.
113.04 square in.
28.26 square in.

Answer 1

the answer is 28.26 square inch.

Answer 2

The answer is 28.26 square in

Explanation:

As, the diameter if the top = 6 inches

And the area of a circle = 3.14(pi) x radius^2

So here radius = Diameter /2 = 6/2 = 3

So radius = 3 inches

So area = 3.14 x (3)^2

= 3.14 x 9

= 28.26 square in
