You are being asked to make π the subject in

C=2πr \:

So divide both sides of the equation by
2r

That is

\frac{ C}{2r} = \frac{2πr}{2r}
The you have
\frac{ C}{2r} = \pi

or

\pi = \frac{ C}{2r}

I hope this is helpful?

IrinaVladis [17]

Answer:

No. Vivian will not make it to her friends house.

Step-by-step explanation:

If Vivian will be riding 15 miles per hour, and she has six hours , then in order to find out the distance, we will have to multiply the rate and the time.

Equation : 15x6 = 90

Using this solution, we can easily find out that 90 is less than 96 as shown.

90<96

In conclusion, no Vivian will not make it to her friends house within the 6 hours she has to get there.

Hope this helps!
