Answer 1

Answer:

34188cm.

Given that:

find the radius of a circle whose circumference is 444cm.

To find:

the radius of circle.

Solution:

Circumference of circle = 2πr

$= 2 \times \frac{22}{7} \times r = 4 \\ = > r = \frac{444 \times 7}{2 \times 22} = 34188cm$

Answer 2

Step-by-step explanation:

34188cm.

Given that:

find the radius of a circle whose circumference is 444cm.

To find:
