If the area of a circle is 28.26 cm2 , what is the radius of the circle?(1 point)

can you explain better?
Answered by GPT 3.5
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.

Given that the area of the circle is 28.26 cm^2, we can plug this value into the formula:
28.26 = πr^2

To solve for the radius, we need to isolate r:
r^2 = 28.26/π
r^2 = 9
r = √9
r = 3

Therefore, the radius of the circle is 3 cm.

Sure! Let's break it down step by step:

1. Given information:
The area of the circle is 28.26 cm^2.

2. The formula for the area of a circle:
The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius.

3. Substitute the given area into the formula:
28.26 = πr^2

4. Solve for the radius:
Divide both sides by π to isolate r^2:
r^2 = 28.26 / π

Calculate the value:
r^2 = 9 approx. (since 28.26 / π ≈ 9)

5. Find the square root of both sides to solve for r:
r = √9
r = 3

Therefore, the radius of the circle is 3 cm.
