Find the area of a circle with a diameter of 22 inches. Use 3.14 for pi

The formula for the area of a circle is A = π r^2

r is the radius, which is half of the diameter.

The diameter is given as 22 inches, the radius would be 2 / 2 = 11 inches.

Area = 3.14 * 11^2

Area = 3.14 * 121

Area = 379.94 square inches.

To do this, use this formula=The area is always pie times the radius to the 2nd (/pi r^{2}). The radius is half the diameter (22/2) which is 11. Now we need to bring this to the power of 2 (11x11), which is 121. Now we multiply by pie (3.14x121) which is 379.94. Your answer is

379.94 inches!
