Question

if the circumference of a citcle are44 cm then find it's radius​

Answer 1

Circumference is 2pie r..... 2*22/7*r=44.....therefore r is equal to 7 cm

Answer 2

Let , the radius be r .

Given ,

Circumference= 44cm

$= > 2\pi \times r = 44cm \\ = > 2 \times \frac{22}{7} \times r = 44cm \\ = > r = \frac{44cm \times 7}{22×2} \\ = > r = 1cm \times 7 \\ = > r = 7cm$

Therefore, radius of the circle=r=7cm
