For this case we have that the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

By clearing the radio we have:

r = \pm \sqrt {\frac {A} {\pi}}

We take the positive value:

r = \sqrt {\frac {A} {\pi}}\\r = \sqrt {\frac {95.03} {\pi}}\\r = 5.50 \ ft

The diameter is twice the radius:

d = 11

Answer:

11 \ ft

<u>Answer:</u>

11 feet

<u>Step-by-step explanation:</u>

We are given the area of a circle and we are to find the diameter of this circle.

We know that the area of a circle is given by \pi r^2 so equating its given value to get:

\pi \times r^2 = 95.03

r ^ 2 = \frac {95.03} {\pi } r = \sqrt {30.25}

r = 5 . 5

Therefore, our required diameter will be 5.5 \times 2 = 11 feet
