Question

The circumference of a circle is 50.24 meters.

What is the diameter, in meters? Use 3.14 for π and round to the nearest meter, if necessary.

Answer 1

hey there!

We know that ,

Circumference is a circle = 2 pi r

=> 2 pi r = 50.24

=> r = 50.24/2 x 3.14

=> r = 78.8 m

But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158

Option d is correct

Answer 2

diameter=16

circumference=radius*2*3.14
50.24=r*2*3.14

1. divide 50.24 by 2
2. divide that answer by 3.14
3. this leaves you with the radius. multiply by 2 for the diameter
