<h3><u>Given</u>:-</h3>
Circumference of a circle = 176 m
<h3><u>To be calculated:- </u></h3>
Calculate the diameter.
<h3><u>Formula used:- </u></h3>
Circumference of circle = 2πr
<h3><u>Solution:-</u></h3>
We know that,
Circumference of circle = 2πr
=> 176 = 2 × 22/7 × r
=> 176 × 7 = 44 × r
=> 1232/44 = r
=> r = 28 m
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
A possible answer for x would be 18
