Your answer will be 15 and for area its 28.26
60
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.
If you are asking about a circle with a circumference of 30" than it would be 9.5".I you mean a radius of 30" than it would be 60".If you mean an area of 30" than it would be 19".
Area of a circle = pi*radius squared
30 inches; the radius of a circle is 1/2 its diameter.
A circle with a 12 inch diameter has a 6 inch radius.
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.
If a circle circumference is 30 the radius is: 4.77
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.
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.
radius of 31 inches
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
