Question

The radius of the circle having the circumference equal to 44cm

Answer 1

Answer:

Step-by-step explanation:

If r is the radius of given circle, then

Circumference 2πr=44cm

Putting π=22/7

2×(22/7)r=44

r=44×7/(22×2)

r=7cm

Now area=πr^2

=(22/7)×7×7

=22×7

=154sq.cm

Answer 2

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