Answer:

Pi is about 3.14. Then the equation for circumfrance is 2(3.14)(R). Then you can first simplify that more to get an approximation of the circumference formula, which is 6.28R. Then you set that equal to the value of the given circumfrance, which is 28(3.14), or 87.92. So:

6.28R = 87.92.

Divide it all by 6.28 to get:

R = 14.

Radius equals to 14.

The time it takes you to get to campus varies inversely as your driving rate. averaging 20 miles per hour in terrible traffic,

Korvikt [17]

Given that the time taken to get to campus is inversely proportional to driving rate, let the time be t and rate be r, thus the function will be written as:'
t=k/r
where
k is the constant of proportionality given by:
k=tr
when r=20 mph, t=1.25 hrs
thus
k=20×1.25
k=25 miles
thus the formula is:
t=25/r
when r=55 mph, the value of t will be:
t=25/55
t=5/11 hours
