Answer :
A = pi * r^2
A = 3.14 * 3.5^2
A = 38.465
38.465/2 = 19.2325 square feet of semicircle
A = 3.14 * 3.5^2
A = 38.465
38.465/2 = 19.2325 square feet of semicircle
A = pi * r^2
R = D / 2
R = 7 / 2
R = 3.5
A = 3.14 * 3.5^2
A = 3.14 * 12.25
A = 38.465
Divide it by 2 since its a semi-circle:
38.465 / 2 = 19.2325
So about 19 square feet.
R = D / 2
R = 7 / 2
R = 3.5
A = 3.14 * 3.5^2
A = 3.14 * 12.25
A = 38.465
Divide it by 2 since its a semi-circle:
38.465 / 2 = 19.2325
So about 19 square feet.
