The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
diameter is 2 times the radius 24
Area = pi*r^2 r(radius) = diameter/2 24 cm/2 = 12 cm radius Area = pi(12 cm)^2 ~ 452 sq cm
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.
24 mm. The diameter is twice the radius.
Radius = diameter/2 = 24 inches
Circumference = 2 x pi x radius = 24 pi 2 x radius = 24 ; radius = 12 units
24
12
6 because the radius is half of the diameter.
radius = 24/2 = 12 units of measurement
