Answer:
The unit rate that Jeremy can row is 1.33 miles per hour.
Step-by-step explanation:
Unit rate is defined as the distance over a time period. The distance that Jeremy can row is given and the time period is given.
The distance (miles)=1/3=0.3333333...
time period: 1/4
0.33333/0.25=1.333333
Given problem;
A =
r²
Solve for π;
To solve for π implies that we make it the subject of the expression.
So;
A = π r²
Now multiply both sides by 
So;
A x
=
x r² x
r² cancels out from the right side and leaves only π;
π = 
So 
The prefix centi- means 10-2
