Question

The two circles shown above have radii of 8 in. and 4 in. What is the Circumference of the both?

Answer 1

Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches

Step-by-step explanation:

Radius of circle 1 = 8 inches

Radius of circle 2 = 4 inches

We need to find circumference of both circles.

The formula used to find the value of circumference is:

$Circumference=2\pi r$

Finding Circumference of Circle 1:

Radius = 8 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*8$

$Circumference=50.24\,\,inches$

Finding Circumference of Circle 2:

Radius = 4 inches

π = 3.14

Putting values and finding circumference

$Circumference=2\pi r$

$Circumference=2*3.14*4$

$Circumference=25.12\,\,inches$

So, Circumference of Circle 1 is 50.24 inches and Circumference of Circle 2 is 25.12 inches
