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 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.
What is the radius of a circle with a diameter of 25 cm?
Radius = 1/2 of the diameter = 12.5 cm.
If the diameter of a circle is 12 cm what is its radius?
Radius of a circle is half of its diameter and so 12/2 = 6 cm
What is the radius of a circle when the diameter is 20cm?
Radius = Diameter/2 = 10 cm
