Question

if the circumference of a circle is 264 cm find its radius​

Answer 1

circumference of circle=2πr
=>264=2×22/7×r
264×7=44r
r=264×7/44
r=42cm

Answer 2

HELLO

$circumference = 2\pi \: r$

$264 = 2 \times \frac{22}{7} \times r$

$r = \frac{264 \times 7}{2 \times 22}$

$r = \frac{132 \times 7}{22}$

$r = 6 \times 7$


$therefore \\ \\ r = 42$
