Question

The radius of a circle is 35cm find its circum ference​

Answer 1

$circumference = 2\pi \: r \\ = 2 \times \frac{22}{7} \times 35 \\ = 2 \times 22 \times 5 \\ = 2 \times 110 = 220 \: cm$

Therefore, Circumference is 220 cm.

Answer 2

Answer:

the radius of the circle is 35 cm.

the circumference of the circle = 2πr.

put the values as given in the question.

we all know the value of π=22/7.

2×22/7×35.

220cm.

it'll surely help you.
