Question

The diameter of a circle is 14 ft. Find its area to the nearest tenth.

Answer 1

Answer:

The answer is 153.9

Step-by-step explanation:

To get the answer we will first divide 14 by 2 because we are trying to find the area.  14 ÷ 2 = 7.  Now multiply 7 x 7 x π, which equals 154.9 rounded to the nearest tenth.

Answer 2

Answer:

153.9 ft.²

Step-by-step explanation:

$A=\pi r^2$ where r is the radius of the circle

The radius is equal to half the diameter, so to find r, divide 14 ft. by 2:

14÷2=7

Plug 7 into the equation as r

$A=\pi (7)^2\\A=\pi (49)\\A=153.9$

Therefore, the area of the circle is 153.9 ft.² when rounded to the nearest tenth.

I hope this helps!
