Question

If the diameter of a circle is 14, what is the area?

Answer 1

`A= 153.9` square units

Explanation:

If you are not familiar with the formula for finding the area by using the diameter, you will have to find the radius first:

`r = d/2`

`r = 14/2 = 7`

`A = pi *r^2" "larr` formula for area

`A = pi xx 7^2`

`A= 153.9` square units
