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.

The answer is 28.26 square in

Step-by-step 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
