14 cm.
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
it is half the diameter e.g 10cm diameter = 5 cm radius
The length of the diameter will be 30 cm if the radius is 15 cm.
16cm
The radius would be 6 cm because the diameter is 2 times bigger than the radius.
14 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
radius 5 cm diameter 10 cm
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
If the diameter is 12 cm the radius is 6 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.
Area of a Circle (A) = pi times the radius (r) squared A = (pi) (r)2 Diameter of a Circle (d) = 2 times the radius (r) d = 2r First, find the r Since the diameter (d) = 70 cm, then 70 cm = 2 r (70 cm)/2 = r r = 35 cm Now that you have found the value of the radius (r), you can plug in r for the equation for the area (A) of a circle: A = (pi) (35 cm)2 A = (pi) 1225 cm2 At this point you can multiply 1225 cm2 by pi with a calculator to get the value of 3848.45100065 which can be simplified to 3848.5 cm2
The diameter would be 14 cm, since the diameter is twice the radius.
If the radius of a circle is 2.5 cm, then its diameter is 5 cm long.
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.
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
