Answer:

79

Explanation:

A square that has side length
l=2 ft has area
2^2=4ft^2.

A circle that has a diameter 20 feet has area
A=(\pi d^2)/(4)

We substitute the diameter into the formula to obtain;


A=(\pi * 20^2)/(4)=100\pi ft^2

The number of squares that has area 4 feet square that can fit into a circle with area
100\pi ft^2 is


=(100\pi)/(4)=25\pi=78.5398

When we round to the nearest whole number; we have 79 squares.
