Find the volume of the bottom and top separately and then add them. Cylinder volume is the area of the bottom times the height (22/7)(5^2)•175=13750 ft^3
The volume of a sphere is V=(4/3)(22/7)r^3 where r is the radius. Here that's also 5 since it fits on the cylinder. Also we only want half the sphere so use V=(2/3)(22/7)•5^3=261.9 ft^3 Which we round upto 262. Now add the parts together 13750+262=14,012 ft^3
<u>Option-(E): </u>Bike B; its wheels have a smaller moment of inertia.
Explanation:
The two cyclists travel at the same speed on level ground, as they approach a low hill and decide to coast up instead of hard pedaling. At the top of the hill, as bike "B" will have a larger speed, as compared to the bike "A".Due, to the effect of having smaller moment of inertia, I=m×r².
Having no friction nor air resistance, and all the wheels roll on the ground without slipping. While, the B have larger speed,v due to the fact that bike "B" will have a larger speed,"v" as compared to the bike "A".
