Question

Find the circumference of a circle of radius 17.5cm.​

Answer 1

Answer:

Circumference of a circle = 2 x R x Pi [3.14 or 22/7]

Step-by-step explanation:

here, R = 17.5

2 x 17.5 x 22/7

= 2 x 2.5 x 22

= 5 x 22

= 110 cm

Hence, the circumference of the circle is 110 cm

Hope this helps you!

Have a great day!

Answer 2

Answer:

The circumference of a circle is 109.9 cm

Step-by-step explanation:

Given-

Radius 17.5cm.

To find-

The circumference of a circle

Solution-

As we know that,

$C=2\pi R$

Where,

C= Circumference

R= Radius

$\pi = 3.14$

Put the given value of radius in equation,

$C=2\times3.14\times17.5$

$C=109.9$ cm

∴ The circumference of a circle is 109.9 cm
