please with formula​

Answer 1

The Diameter of the circle is 20cm.

Explanation:

Given:

1. Radius = 10cm

To find:

Diameter

Formula:

Diameter = 2× Radius

Solution:

==> Radius = 10cm

==> Substitute the radius value in the given Formula

==> Diameter = 2× Radius

==> Diameter = 2× 10

==> Diameter = 20 cm

The Diameter of the circle is 20cm.

Answer 2

Answer:

Hence the diameter of the circle is 20cm.

Step-by-step explanation:

As per the data given in the above question,

The given data is radius of a circle is 10cm,

We have to find the diameter of the above circle.

Here we have to use the formula of diameter,

Diameter of the circle is $=2\times radius$

Substitute the value of radius that is 10cm in above equation we get,

$D=2\times 10\\D=20cm$

Hence the diameter of the circle is 20cm.
