The radius is 1.27cm
A radius (not raduis) of 15 units implies a circumference of 94 units.
Circumference of a circle = 2*pi*radius or diameter*pi
94.248 feet.
A circle with a radius of 15 inches has a circumference of: 94.2 inches.
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
Radius is 2.39
Radius is 2.39

A circle with a circumference of 15pi (47.1238898 units) has a radius of: 7.5 units
The radius is 1.27cm
A radius (not raduis) of 15 units implies a circumference of 94 units.
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
Circumference of a circle = 2*pi*radius or diameter*pi
