A porch has the shape of a semicircle with a diameter of 7 ft.

What is the approximate area of the porch, rounded to the nearest square foot? Use 3.14 to approximate .

ft2

Sagot :

A = pi * r^2 

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.
