Answer:
43.65 cm squared
Step-by-step explanation:
Volume of a sphere with radius of 70 feet is:

where r is that radius
Because we need quarter sized tank of that radius we need to divide formula for volume by 4
Than we get:

V = 359188,76
Rounded:
V = 359189
Perimeter=(2*length)+(2*width)
length=2*w
132=(2(2w))+(2w)
132=(4w)+(2w)
132=6w
w=22
l=44
