Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
3.7 inches, approx.
A sphere of radius 12 inches cannot have a height of 23 inches. It is, in that case, a flattened sphere and a lot more detailed information about the flattening is required to find its volume.
If the diameter is 6 inches, then the radius is 3 inches.
Radius is merely..., diameter/2 3 inches/2 = 1.5 inches in radius ==============
Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
Circumference = 2 * Pi * radius Radius = 23 / (2 * Pi) Radius = 3.66 inches
11.5 inches for a 23-inch diameter circle. If you meant the circumference is 23 inches, then the radius would be 3.6606 inches.
The radius is 5.41 inches.
you times it by 3.14 but if you get a radius you timesit by 2, then by 3.14
Circumference of the circle: 2*23*pi = 46*pi inches
3.7 inches, approx.
A sphere of radius 12 inches cannot have a height of 23 inches. It is, in that case, a flattened sphere and a lot more detailed information about the flattening is required to find its volume.
Volume = 3,468.31829 in3
Volume = 1/3*pi*122*23 = 3468.318 cubic inches to 3 d.p.
r=d/2 c=Pi*d 2*r=d c=Pi*2*r where c is the circumference r is the radius and d is the diameter
The radius is 8 inches.
