The area of a circle is 25π square inches. What is the length of the radius of the circle in inches? (Area of circle = πr^2). I don't understand it please explain it to me
When the north-south is attract with a compass so the compass were attract magnet together too.
To find the length of the radius, we need to rearrange the formula for the area of a circle which is given as A = πr^2.
First, let's substitute the area value given in the problem, which is 25π square inches. So we have:
25π = πr^2
Now, to solve for r, we need to isolate it. The first step is to divide both sides of the equation by π:
25π / π = r^2
On simplifying, we get:
25 = r^2
Next, we need to find the square root of both sides to solve for r:
√25 = √r^2
On simplifying, we have:
5 = r
Therefore, the length of the radius of the circle is 5 inches.
