Question

circumference of a circular sheet is 154 cm. Find its radius.

Answer 1

Heya mate!!

$2\pi \: r = 154 \\ 2 \times \frac{22}{7} \times r = 154$

$r = 154 \times \frac{7}{44}$

$r = 24.5$

Hope it helps u dear✌️✌️

Answer 2

$2\pi \: r = 154cm \\ \\ 2 \times \frac{22}{7} \times r = 154 \\ \\ r = 154 \times \frac{7}{22 \times 2} \\ \\ 24.5$
