Depends on what 28 cm is. The radius? The diameter?
Assuming it's the radius, using the formula for the volume of a sphere (
), we get about 91,952 cubic centimeters, which is closest to 92,000.

Answer:
Ramp
Step-by-step explanation:
A ramp is easier for a person to go up or down on because it is just higher sloped ground. For a person with crutches, a ramp does not have any abnormal steps for them to try and get over with one leg.
X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
