circumference of a circle = 2*pi*radius or diameter*pi
C=2 pi R
The radius is 7cm
14 cm.
The diameter of a circle is twice its radius
7cm; the diameter of a circle is twice its radius.
circumference of a circle = 2*pi*radius or diameter*pi
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
C=2 pi R
3.14
The radius is 7cm
14 cm.
The diameter of a circle is twice its radius
1.7
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
