Question

If the radius of a circle is 10.5 cm. Find the diameter *​

Answer 1

Answer:

radius is half of diameter.

d= r×2

= 10.5×2

=21.

= The diameter of circle is 21 cm

Answer 2

Answer:

Diameter of circle is 21 cm .

Step-by-step explanation:

Given information,

Radius of circle is 10.5 cm.

We have to find out the value of The diameter of a circle.

Diameter is a straight line from one side to the other side that passes through the center point of a circle.

Radius is half of diameter .

As we know that ,

Radius is half of diameter.

Radius = $\frac{diameter}{2}$

Diameter = Radius × 2

As per the given data ,

Diameter = 10.5 × 2

By dividing by 2 we get

Radius = 21.0

Hence,

Diameter of circle is 21 cm .
