Answer 1

Step-by-step explanation:

circumference = 2pir

= 2 × 22/7 ×7

= 2×22

=44cm

Answer 2

Answer:

Circumference of circle is 43.96 cm.

Step-by-step explanation:

As per given information ,

Radius of circle is 7 cm.

We have to find out the circumference of circle.

As we know that,

Circumference of circle = $2 \times \pi \times r$

Where,

r = radius of circle.

Put the value of r = 7 cm ,

Circumference of circle = $2 \times \pi \times 7$

Circumference of circle = $14\times \pi$

Put the value of π = 3.14

Circumference of circle = $14\times 3.14$

Circumference of circle = $43.96$

Hence,

Circumference of circle is 43.96 cm.
