Question

The ratio of the circumference and diameter of a circle is 22:7. If the diameter of the circle is 42m, what
is the length of its circumference?​

please answer

Answer 1

Diameter= 42

radius= 42÷2=21

Circumference= 2πr

= 2×22÷7×21= 132m

Answer 2

Answer:

132 m is the circumference of given circle

Step-by-step explanation:

ratio of circumference and diameter is 22:7

diameter is 42 m

let the circumference of circle be x

22/7 = x/42

x = 22 x 42/7

x = 22 x 6

x = 132 m
