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.
Oh, what a delightful question! To find the radius of a circle, we simply divide the diameter by 2. So, if the circle is 24 feet across, the radius would be 12 feet. Just imagine all the happy little circles you can create with that radius!
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.
