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!
Oh, dude, the radius of a circle is just half of the diameter, so for an 11-inch circle, the radius would be 5.5 inches. Like, it's just basic math, nothing to lose sleep over. So yeah, the radius is 5.5 inches, but who's really measuring, right?
radius = b/2*pi
