What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
What is a circle's diameter if the radius is 7 cm?
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
What is the radius of a circle if its diameter is cm?
The radius of a circle is half of its diameter
What is the diameter of a circle with a radius of 12cm?
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
What is the radius of a circle that has a 10 cm diameter?
The radius of a circle is half the length of its diameter. Therefore, if the diameter of the circle is 10 cm, the radius would be half of that, which is 5 cm. The formula to find the radius of a circle is r = d/2, where r is the radius and d is the diameter.
