Question

If the radius
of a circle is 7cm find its circumference
radius

Answer 1

Radius=7cm
CIRCUMFERANCE=2πr
π=22/7
R=7cm

so,
2×22/7×7
44cm
CIRCUMFERANCE=44cm

Answer 2

radius of circle = 7cm

circumference of circle = 2πr

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

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: 44 \: cm {}^{2}$
