<u>Solution for Q1:</u>
Given is the height of ice-cream cone, h = 6 inches.
Given is the diameter of ice-cream cone, d = 2 inches. Then radius of cone would be half of diameter, r = d/2 = 1 inch.
The ice-cream without scoop would be in the shape of cone only. So we need to find the volume of cone.
We know the formula for volume of cone is given as follows :-
So the volume is 6.28 ≈ 6 in³.
Hence, option A is correct i.e. 6 cubic inches.
<u>Solution for Q2:</u>
A candy is in shape of sphere with diameter, d = 0.25 inches.
Then radius of sphere, r = d/2 = 0.250/2 = 0.125 inches.
The formula for volume of sphere is given as follows :-
So, volume of one candy = 0.00818123 cubic inches.
There are total 120 candies in the machine.
Total volume of all 120 candies = 120 x 0.00818123 = 0.981748 cubic inches.
Hence, the total volume of all candies in the machine is about 0.982 in³.
