to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
The radius of a circle is half of its diameter. If the diameter of the circle is 150 cm, then the radius would be half of that, which is 75 cm. The radius is the distance from the center of the circle to any point on its circumference.
diameter = 2*radius
The diameter of a circle is twice its radius.
75
radius = square root of (75/pi) = 4.886025119 diameter = 2*radius = 9.772050238 or 10 mm to the nearest integer
to get the radius of a circle given the diameter, than simply divide the diameter by 2 to get the radius. in this case, the answer to your question would be 37.5 cm. hope this helps!!!
0.375 (r = d/2).
.75 inches or 19 Millimeters is the diameter so the radius is .375 inches or 9.5 Millimeters.
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
A radius is half of a diameter. Example Diameter:4 Radius:2
