it is half the diameter e.g 10cm diameter = 5 cm radius
The circumference of a 5 cm circle is: 15.71 cm(diameter x pi = circumference).
radius = diameter ÷ 2 ⇒ radius = 10 cm ÷ 2 = 5 cm
To get the radius just divide the diameter by 2. so, 10/2 = 5 cm
The diameter of a 10 cm wide circle is 10 cm. The diameter is just how wide it is. The radius is 1/2 X diameter. 1/2 X 10cm = 5 cm.
10 cm; the diameter of a circle is twice its radius.
10 cm
radius 5 cm diameter 10 cm
10 cm (diameter is double the radius)
5 cm
it is half the diameter e.g 10cm diameter = 5 cm radius
If the diameter of the circle is 5 cm then its circumference is: 5*pi cm
Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.
Around 19.634375 cm
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
Radius = diameter/2 = 5 cm
The circumference of a 5 cm circle is: 15.71 cm(diameter x pi = circumference).
