Answer:
1017.9 cm³
Step-by-step explanation:
Since the sphere is only sitting on the cylinder and they want a solid brass trophy, you can just take the volume of each shape and add them together.
•Volume of a Sphere = (4/3)πr³
•Volume of a Cylinder = πr²
•Radius of a Sphere = (1/2) Diameter
Plugging in the given info should give 1017.9 (assuming I input the values correctly).

Step-by-step explanation:
Step 1; First, we convert the given fractions into improper ones. To do this, we multiply the whole number with the denominator of the fraction and add with it the same fraction's numerator whereas the denominator remains unchanged. To convert the fraction
3 = (3 × 4) + 1 / 4 =
,
2 = (2 × 3) + 1 / 3 =
,
6 = (6 × 5) + 1 / 5 =
,
4 = (4 × 4) + 1 / 4 =
,
5 = (5 × 7) + 2 / 7 =
,
4 = (4 × 3) + 1 / 3 =
.
Step 2; Now we subtract, using LCM to arrive at the answer
