Question

The area of a circle is 113.04m². find its radius.​

Answer 1

Answer: Radius is 6 meters

Step-by-step explanation:

The formula for the area, A, of a circle = πr², where r is the radius of the circle.

We’ll use the value of 3.14 as our approximation for the irrational number π.

the area of a circle is 113.04 square meters

A = πr²

πr² = A (since equality is symmetrical, i.e., if a = b, then b = a)

πr²/π = A/π

r² = A/π

r² = (113.04 m²)/3.14

r² = 36 m²

Now, taking the square root of both sides, we get:

√r² = ±√(36 m²)

r = ± 6 meters

Since we physically can’t have a negative distance, then the radius

r = 6 meters.
