Answer:

Step-by-step explanation:
The area of the circumference of a circle is:

We know that r is 8, so we can plug that into the formula.
However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).

Answer:
The unit rate is<u> 1.25 seconds per jump</u>.
Step-by-step explanation:
Given:
Will can jump rope at a rate of 8 jumps for every 10 seconds.
Now, to find the unit rate:
So, by dividing we get the unit rate.
At the rate of 8 jumps Will takes 10 seconds.
Thus, for the rate of 1 jump he will take = 
Therefore, the unit rate is 1.25 seconds per jump.
