The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
The equation of a circle is defined by:
(x-h)^2+(y-k)^2=r^2
Where (h,k) s the center and r is the radius.
We can translate the word problem into (x+2)^2+(y-8)^2=16
:)

Answer:
10 feet
Step-by-step explanation:
pythagorean theorem
First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.
However, if you want the approximation, simply plug it into your calculator and get 4.18154055.
