Question

The area of a circle is 36 square feet. What is the diameter?

Answer 1

`area = \pi {r}^(2)`

`36 = 3.14 * {r}^(2)`

`(36)/(3.14) = {r}^(2)`

`{r}^(2) = 11.46`

`r = √(11.46)`

`r = 3.39`

`diameter = 2 * radius`

`diameter = 3.39 * 2`

`= 6.78`

Answer 2

The diameter is 6.76

Please read the exaplanation... it always helps!

Explanation:

Area of circle = r^2 pi

if the area is 36 then...

36 = r^2 pi to solve for r divide both sides by pi

36/pi = r^2

11.45 = r^2 take the square root of both sides

√11.45 = r RADIUS = 3.38

then multiply by two since the diameter is 2 (radius) and you get...

diameter = 6.76

i hope this helpssssss!!!!!!!
