Question

find the circumference of the circle with the following radius 22upon 7 a) 14cm

Answer 1

Circumference of Circle is
$2\pi \: r$
2× 22/7 ×22/7
2cm

Answer 2

Heya mate,Here is ur answer


We know the formula

Circumference of a circle =2πr

1) Radius = 22/7

Circumference of the circle=
$2\pi \: r$


$= 2 \times \frac{22}{7} \times \frac{22}{7}$


$= \frac{968}{49}$


$= 19.75 \: cm \: (approx)$


2)Radius =14 cm

Circumference of the circle=2πr


$= 2 \times \frac{22}{7} \times 14$

$= 88 \: cm$
