Question

If radius of a circle is 10cm, then find it's diameter.​

Answer 1

Answer:

Diameter is the longest line that you can draw in a circle passing through the centre of the circle.

Radius is the line joining the centre of the circle to any point on the circumference.

Radius = 1/2 × diameter

Diameter = 2 × radius

Accordingly

10 cm diameter circle radius = 10/2

Radius = 5 cm

Answer: the radius of 10 cm diameter circle is 5 cm.

Answer 2

Answer:

Diameter is 20cm

Step-by-step explanation:

Given that

Radius of circle is 10cm

To find

Diameter of circle.

Solution

As we know that,

Diameter of circle is always two times of radius of circle hence as radius is given we can calculate diameter as

$diameter \: of \: circle = 2 \times 10$

by multiplication we get

$diameter \: of \: circle = 20cm$
