Answer 1

Answer:

radius = 7cm

circumference = 2 pi r

2 22/7 x 7

44 cm

Step-by-step explanation:

Answer 2

Answer:

44cm.

Step-by-step explanation:

The circumference of a circle is given by:

C = 2πr, where r is the radius of the circle.

π is approximated as 22/7.

So, C = 2 * (22/7) * 7 cm = 2 * 22 cm = 44cm.
