double the radius to get the diameter = 30
multiply by pi (3.1415...) = 92.245 cm
The radius is 1.27cm
The formula for the circumference of a circle is C = 2πr where r is the radius. This formula can also be expressed as C = πd where d is the diameter as the diameter is twice the radius. C = 15π = 47.12cm (2dp)
circumference = 15*pi cm
If a circle circumference is 30 the radius is: 4.77
The circumference of a circle with a 2pi radius is: 39.58
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
The radius is 1.27cm
The circumference of a circle with diameter of 15cm is about 47.12cm
The circumference of a circle, if the diameter is 15cm, is about 47.12cm
The circumference of a circle with diameter of 15cm is about 47.12cm
The formula for the circumference of a circle is C = 2πr where r is the radius. This formula can also be expressed as C = πd where d is the diameter as the diameter is twice the radius. C = 15π = 47.12cm (2dp)
circumference = 15*pi cm
