Lesson Steps

Step	Type	Explanation	Answer
1	Problem	The circumference is 56 inches. What is the radius?(π = 3.14)
2	Step	The circumference of a circle is	56 inches

Answer

Problem

The circumference is 56 inches. What is the radius?(π = 3.14)

Step

The circumference of a circle is

56 inches

Formula

Circumference of a circle(c)

C = 2πr

Step

Now plug the values into the formula

\$56 = 2 \times 3.14 \times r\$

Step

After simplification

\$56 = 6.28 r\$

Step

Divide 6.28 on both sides.

\$56/6.28 = (6.28 r)/6.28\$

Step

After simplification

r = 8.917

Step

So, the radius of a circle is 8.917 inches.
