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 inches has an area of 452.39 square inches.
pi*25 = 78.5.
To find the radius of a circle when given the circumference, you can use the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 62.8 inches, you can plug this value into the formula: 62.8 = 2πr. Solving for r, you get r ≈ 9.98 inches. Therefore, the approximate radius of a circle with a circumference of 62.8 inches is 9.98 inches.
r = 7.421 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 inches has an area of 452.39 square inches.
Radius = 1/2 of diameter = 7/2 = 3.5 inches
pi*25 = 78.5.
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
C = 2*pi*r C = 37.69911184 inches or 38 inches to two significant figures.
The approximate radius is five (5) inches.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
The radius of a circle is half the diameter, so to find the radius of a circle with a diameter of 11 inches, you would divide 11 by 2. Therefore, the radius for a circle with a diameter of 11 inches is 5.5 inches.
radius = b/2*pi
