Radius of circle is the square root of 154/pi = 7 units rounded
The area of a circle is 153.86cm².find the radius of the circle
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
Radius = +sqrt(Area/pi)
A = (pi)r^278.6 = (pi)r^2r = 5.002 cm
the radius is from the center of the circle to the edge so that's how you find the radius.
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
pi*25 = 78.5.
64pi (miles square)
In a circle, the area of the circle is pi times the radius squared
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
