Question

A circle has a diameter of 14 ft. What is the area of the circle? (use 3.14 for )

A. 43.96 ft²
B. 87.92 ft²
C. 153.86 ft²
D. 615.44 ft²

Answer 1

answer is C. 153.86ft^2

Answer 2

C 153.86ft²

Explanation:

The formula is πr²

This mean you first find the radius of the circle which is half of the diameter. so for this circle the radius is 7ft.

Now plug everything in the formula and solve

3.14×7²

Following bedmas you would do exponents first. 7²=49

Now do 3.14×49 which is 154.86ft²
