The volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.
We have given that, the radius of the sphere is 9.1ft.
We have to determine the volume of the sphere
<h3>What is the formula for the volume of the sphere?</h3>
The volume of the sphere is given by
r is the radius of the sphere
V- is the volume of the sphere
So use the given value in the formula so that,
Therefore the volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.

Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
