Question

Fiona draws a circle with a diameter of 14 meters. What is the area of Fiona’s circle?

7Pi meters squared
14Pi meters squared
28Pi meters squared
49Pi meters squared

Answer 1

D

Explanation:

i just took the test

Answer 2

49Pi meters squared

Explanation:

we know that

The area of a circle is given by the formula

`A=\pi r^(2)`

where

r is the radius

Remember that

The radius is half the diameter

so

`r=14/2=7\ m`

substitute

`A=\pi (7)^(2)`

`A=49\pi\ m^2`
