Question

the radius of circle is 25 cm. what is the circumference and diameter of the circle​

Answer 1

Answer:

circumference of circle =2πr

=2×22/7×25

=1100/7

= 157.14

diameter of circle =2r

= 2×25

= 50

Answer 2

Given:

Radius=25cm

To find:

The circle's circumference and the diameter

Solution:

The required circumference is 157.14 cm and the diameter is 50 cm.

We can obtain the required values by using the given formula.

The circle's circumference=2πr

Here r is the circle's radius.

So, circumference=2×22/7×25

=44/7×25

=157.14 cm

Now, the circle's diameter can be obtained by doubling the radius given.

Since diameter=2(radius), the value of diameter=2×25

=50 cm

Therefore, the required circumference is 157.14 cm and the diameter is 50 cm.
