Question

This is new stuff for me I don’t know how to solve this word problem and my teacher was absent today so I didn’t have any clarification

Answer 1

we have that

The formula to calculate the circumference of a circle is equal to

`C=2\pi r`

Solve for r

That means

Isolate the variable r

so

Divide on both sides of the formula by 2pi

`(C)/(2\pi)=(2\pi r)/(2\pi)`

Simplify

`r=(C)/(2\pi)`

For

C=75.3 m

and

pi=3.14

substitute in the new formula

`\begin{gathered} r=(75.3)/(2(3.14)) \\ r=12.0\text{ m} \end{gathered}`
