It might help if the question indicated whether 5 cm referred to diameter or circumference or something else. Until then, the question cannot be answered and is simply a waste of everyone's time.
it is half the diameter e.g 10cm diameter = 5 cm radius
Radius = 5/(2*pi) = 0.7958 cm rounded to 4 decimal places
radius = diameter ÷ 2 ⇒ radius = 10 cm ÷ 2 = 5 cm
A = 78.54 cm2
If the circumference of a circle is 12 cm the radius is: 1.91 cm
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
10 cm; the diameter of a circle is twice its radius.
10 cm
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.
radius 5 cm diameter 10 cm
The circumference of a circle 5cm in radius is about 31.42cm
10 cm (diameter is double the radius)
5 cm
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
it is half the diameter e.g 10cm diameter = 5 cm radius
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
