Question

if the diameter of a circle is 10cm what will its radius be​

Answer 1

The radius is 5cm.

Radius of a circle is half of the diameter so we can say

diameter/2=radius

Answer 2

Answer:

5 cm

Step-by-step explanation:

Radius = Diameter / 2

= 10 / 2

Radius = 5 cm

( You, please study the formula,

1. Radius = Diameter / 2

2. 2 × Radius = Diameter

This is an easy formula and easy to memorize. If you study maths with interest, you can do any sums on your own, without anybody's help. )
