Just draw the graphs, and you should find y = 10x² is the only graph narrower than the given one.
Answer:
Volume of the sphere is 
Step-by-step explanation:
It is given diameter of the sphere d = 6 cm = 0.06 m
Radius of the sphere

We know that volume of the sphere is given by

Therefore ,


Therefore volume of the sphere is 
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
It only has one solution. x= 16 and y = -12
