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
A= pie radius squared
25= (3.14)(radius squared)
3.14 × (N)(N) = 25
Answer= 2.82
25pi = pir^2
so
25 = r^2
5 = r
r = 5
Thanks
To find the length of the radius of the circle, we can use the formula for the area of a circle, which is A = πr^2. In this case, we are given that the area of the circle is 25π square inches.
To solve for the radius, we need to isolate the variable "r" in the equation. We can do this by dividing both sides of the equation by π.
A/π = r^2
Now we can substitute the given value for the area.
(25π)/π = r^2
Simplifying the left side of the equation, we get:
25 = r^2
To solve for r, we can take the square root of both sides of the equation.
√(25) = √(r^2)
Simplifying further, we get:
5 = r
Therefore, the length of the radius of the circle is 5 inches.
