Question

What is the circumference of the circle? Use 22/7 for pi

Answer 1

The second choice, 55 cm.

Explanation:

Formula for circumference:

`\pi * d`

`(22)/(7) * (35)/(2) = (770)/(14)  \\\\770 / 14 = 55`

The circumference of the circle is 55 cm.

Answer 2

Circumference of circle is:

55 cm

Explanation:

we are given diameter d of a circle=35/2 cm

We have to find its circumference.

We know that circumference of circle in terms of its diameter is:

Circumference=πd

Circumference=
`(22)/(7)* (35)/(2)`

=55 cm

Hence, circumference of circle is:

55 cm
