Answer is B)
Answer:

Step-by-step explanation:
Given


Required
How far did they row together
To do this, we simply add the distance they both covered.

This gives;

Take LCM


Simplify

<em>Hence, they both rowed 1/2 mile</em>
The area of a circle of radius r is pi*r^2
Hence here the area is A=5^2*pi=25pi~78.5 square inches
