Every circle has a point called the centre. A straight line drawn through the centre and extending both ways to intersect with the circle at opposite points is called the diameter. A straight line drawn from the centre to intersect with one point of the circle is called the radius. In this case, the length of that straight line is 12 inches.
A circle with a radius of 5.1 inches has an area of 81.71 square inches.
A cylinder with a radius of 4 inches and a height of 12 inches has a volume of 603.186 cubic inches.
Neither of the two is correct. It would be 12 inches equals a foot or 144 inches equals 12 feet.
diameter = 2 X radius = 12 inches
The circumference of a circle if the radius is 12 equals about 75.4
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
A circle with a radius of 5.1 inches has an area of 81.71 square inches.
A circle with a radius of 12 inches has a circumference of 75.4 inches.
A cylinder with a radius of 4 inches and a height of 12 inches has a volume of 603.186 cubic inches.
Neither of the two is correct. It would be 12 inches equals a foot or 144 inches equals 12 feet.
diameter = 2 X radius = 12 inches
12 inches
The circumference of a circle if the radius is 12 equals about 75.4
A cone with a base radius of 4 inches and a height of 12 inches has a volume of 201.06 cubic inches.
The surface area of a cylinder that has a radius of 6 inches and a height of 12 inches is 678.58 square inches.
Radius = 1/2 of the diameter = 6 inches
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
