If the diameter is 12 cm the radius is 6 cm.
Radius of a circle is half of its diameter and so 12/2 = 6 cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
The radius is: 1.91 cm
6 cm. The radius is 1/2 of the diameter.
Area of ANY circle is (pi) x (radius)2 .
12 cm.
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The radius of the circle is: 9.549 cm
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
