Area of the circle=πr²
25π = πr²
25 = r²
We need only positive root.
√25 = √r
r= 5 inch
25π = πr²
25 = r²
We need only positive root.
√25 = √r
r= 5 inch
The required length of the radius of the circle is 5 inches long.
Given that,
The area enclosed by a circle is 25 pi square inches. what is the length, in inches, of the radius of the circle is to be determined.
What is a circle?
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,|
The area of the circle is 25π inches²
Area of the circle = πr²
Now,
πr² = 25π
r² = 25
r = √25
r = 5
The radius of the circle is 5 inches long.
Thus, the required length of the radius of the circle is 5 inches long.
