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
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.
