Convert the circumference into milimeters and divide by pi (~3.14159)
707 mm2
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.
If the measurement of eleven millimeters refers to the diameter of the circle, then the radius would be half of that, which is 5.5 millimeters. If the eleven millimeters is already the radius, then it remains 11 millimeters. Please clarify if you meant diameter or radius for a precise answer.
The radius of a circle is half of its diameter. If the radius is given as 16.3 millimeters, that means the distance from the center of the circle to its edge is 16.3 millimeters. Therefore, the radius itself is simply 16.3 millimeters.
A circle with a radius of 9.6 millimeters has a circumference of 60.32 millimeters.
Volume = 1/3*pi*42*9 = 150.7964474 cubic millimeters
The volume of a sphere that has a radius of 10 millimeters is: 4,189 mm3
Radius = 1/2 of the diameter = 328/2 = 164 millimeters
.75 inches or 19 Millimeters is the diameter so the radius is .375 inches or 9.5 Millimeters.
20 millimeters
Well, honey, the radius of a circle is the distance from the center to any point on the edge. So, if you want it in millimeters, just measure that distance in millimeters. It's as simple as that, darling.
The radius would be 7 millimeters.
