the formula for the circumference of a circle is pi*diameter.
the diameter is 2*radius
so if 1.5 is the radius, 3 is the diameter
plug 3 into the formula...
circumference=3.14*3
circumference=9.42

The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
The radius is 15 feet 2r=30 30/2=15 15 is the radius
The area of a circle has the formula πr2 This means pi x radius squared. If the radius is 15. Square 15- 15x15. Multiply it by pi(3.14159265) Answer is 706.9mm2
The radius is 1.27cm
