90-7 =83 degrees
height = 3 miles
divide 3 by the cos of 83 degrees
3/cos(83) = 24.6165
rounded to nearest mile = 25 miles

Answer:
36000pi
Step-by-step explanation:
V = 4/3*pi*r^3 so we need to know r
we know surface area, which is 4pi*r^2=3600pi. so we can solve for r
r=30
so v = 4/3*pi*30^3 = 36000pi
