The radius is 1.27cm

A radius (not raduis) of 15 units implies a circumference of 94 units.

Circumference = 2*pi*rCircumference = 2*pi(15 inches)= 94 inches========

Circumference of a circle = 2*pi*radius or diameter*pi

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

Circumference = 2*pi*rCircumference = 2*pi(15 inches)= 94 inches========

The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
