How do you find the radius of a circle given the diameter?
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
Find the radius of a circle whose diameter is 7 inches?
Radius = 1/2 of diameter = 7/2 = 3.5 inches
How do you find the diameter and radius of a circle with a circumference of 36 inches?
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
How do you find the diameter and radius of a circle with a circumference of 48 inches?
To find the diameter, 48/pi To find the radius, (48/pi) then divide by 2 :)
How do you find the diameter and radius of a circle with a circumference of 2 inches?
Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches
What would be the radius of a circle with a diameter of 8 inches?
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.

Find the radius of a circle whose diameter is 7 inches?
Radius = 1/2 of diameter = 7/2 = 3.5 inches
Will a circle with a radius of 4 inches fit inside a circle with a diameter of 5 inches?
no because the radius is half the diameter so it must be multiplied by two in order to find the diameter of that circle which is 4 times 4 equals to 8 so the circle which has a diameter of 5 inches is much to small for a circle with a radius of 4 inches to fit.

How do you find the diameter and radius of a circle with a circumference of 37 inches?
diameter = circumference/pi = 37/3.1416 = 11.8 inches; radius = 1/2 diameter = 5.9 inches; radius = circumference/(2pi) = 5.9 inches = 37/6.2832 = 5.9 inches
Radius of a circle is 8 inches how do you find the diameter?
Think of a diameter as two radii in a straight line...
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
How do you find the circumference of a circle if you know the radius?
Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches
How do you find the radius of a circle from the diameter?
the radius is half the diameter
