Find the diameter of a circle with an area of 95.03 square feet

Leona [35]

Answer:

diameter ≈ 11 feet

Step-by-step explanation:

The area (A) of a circle is calculated using the formula

A = πr² ← r is the radius

To find r divide both sides of the equation by π

r² = $\frac{A}{\pi }$ = $\frac{95.03}{\pi }$

Take the square root of both sides

r = $\sqrt{\frac{95.03}{\pi } }$ ≈ 5.5 feet

Diameter = 2r = 2 × 5.5 = 11 feet
