the radius of a circle is half of its diameter.
10 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.
To get the radius just divide the diameter by 2. so, 10/2 = 5 cm
radius = diameter ÷ 2 ⇒ radius = 10 cm ÷ 2 = 5 cm
radius 5 cm diameter 10 cm
10 cm; the diameter of a circle is twice its radius.
The area of a circle whose diameter is 10 cm is: 78.54 cm2
10 cm
the radius of a circle is half of its diameter.
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
10 cm (diameter is double the radius)
5 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.
10 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.
Radius = Diameter/2 = 10 cm
