Find the area of the circle. Leave your answer in terms of pi.

The diameter of the circle is 14 so I know the radius is 7.

I think I have to do this:

3.14 * 7

But I'm not sure if that's right but if it is I'm not sure what to do after.

So the answer choices are:

A: 7 pi square feet
B: 14 pi square feet
C: 28 pi square feet
D: 49 pi square feet

Help??

Answer:

49 pi feet

Step-by-step explanation:

Area of a circle = πr²

Diameter= 14

Radius= diameter/2

r = 14/2

= 7

Area of circle = π7²

Ï€49

Answer= 49 pi feet

Correct response:

  • The area of the circle is D: 49 pi square feet

Methods used to calculate for the area

The given diameter of the circle, D = 14 feet

Required:

To find the area of the circle.

Solution:

The area of a circle given the diameter is found using the following

formula;

[tex]Area \ of \ a \ circle, \ A = \mathbf{\pi \times \dfrac{D^2}{4} }[/tex]

Therefore;

[tex]A = \pi \times \dfrac{14^2}{4} = \mathbf{49 \cdot \pi}[/tex]

The area of the circle, A = 49·π ft.²

The correct option is therefore;

D: 49 pi square feet
