Question

The circumference of a circular painting is 25.12 feet. What is the radius of the painting? Use 3.14 for A and do not round your answer.

Answer 1

Step-by-step explanation:

The formula of the circumference of a circle is:

`C=2\pi r`

We have C = 25.12 ft and we have to use 3.14 for pi. Replacing and solving for r:

`\begin{gathered} 25.12=2\cdot3.14\cdot r \\ r=(25.12)/(2\cdot3.14) \\ r=(25.12)/(6.28) \\ r=4 \end{gathered}`

Answer:

r = 4 feet
