Question

The circumference of a circle is 308 cm, find its radius.​

Answer 1

Answer:

196cm

$2\pi \: r = 308$

$308 \times 2 \times \frac{7}{22}$

$r = \frac{308 \times 14}{22}$

$\frac{4312}{22}$

$r = 196$

Answer 2

Answer:

circumference = 2πr

308 = 2πr

=> 2πr = 308

=> r = 308 × 7 / 2 × 22 = 49

=> r = 49
