Answer:</h2>
Luke does a work of 308Nm
<h2>
Step-by-step explanation:</h2>
If we have a constant force 
that acts on a body in the same direction as the displacement 
, then the work 
is defined as the product of the force magnitude 
and the displacement magnitude 
. In other words:
, which is valid for a constant force in direction of straight-line displacement.
In this problem:
Therefore:
Answer:
79
Step-by-step explanation:
The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79
Answer:
