S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
The next 2 answers are: -2/5 and -3/5
So we start out by finding out what 80% of 500 is by,
500 * .80 = 400
So if 80% is 400 that means that there is still space available for 100 more gallons!
How the heck did we know that?!?
simple 500- 400= 100
So that leaves us knowing that there are 100 gallons left that can be held!! :)
So your answer is 100 gallons!!
I hope that this helped!
Answer:
Step-by-step explanation:

Given the figure of a square pyramid
The area pf the base =area of the square of side 14 in =
the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in
so, the area of the sides =
So, the surface area of the pyramid =
So, the answer will be A = 532 in^2
