We can use the slope formula:

By plugging the values into this formula, we can solve for the slope.
-1 - 4 / -8 - 0
-5 / -8
Because there are two negatives, they cancel out;
The slope is 5/8
The formula, the area for the circles, the semicircles, the area for the quarter circles, and the total area
A for circles=1571
A for semicircles=1571
A for quarter circles=7854
A for all circles= 10995.98
1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m
2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625 (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15
Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000
The answer is the second choice or B.
