Your answer will be 15 and for area its 28.26
A circle with a 12 inch diameter has a 6 inch radius.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
Area of a circle: pi times radius squared
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
Oh, dude, the diameter of a circle is just the distance across the circle passing through the center. So, if you have a 30-inch circle, the diameter would be 30 inches. It's like the circle's belly button - right in the middle, measuring from one side to the other.
Area of a circle = pi*radius squared
A circle with a 12 inch diameter has a 6 inch radius.
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
The radius of a circle with a 14.5 inch circumference is 2.15 inches
A four-inch radius circle has an area of about 50.27 square inches.
You can calculate the area of a circle with the formula: A = pi x radius2 If the 30 inches refers to the diameter, divide it by 2 to get the radius.
If a circle circumference is 30 the radius is: 4.77
12 inch
1 inch
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
radius of 31 inches
