(a)
To find: the amount of ice in the icicle
(a)

Answer to Problem 17PPS
The amount of ice in the cone is approximately
Explanation of Solution
Given:
Diameterof cone is l.5 ft
Height is 2.5 ft
Calculation:
The objective is to find the amount of ice in the cone.
Since the amount of ice is the volume of the cone, so find the volume of the cone
The volume V of a cone is given by the formula
Where
Since radius is half the diameter of a circle, so radius of the circle is
The area B of the circle is given
Put
Thus, the volume V of the cone is
Therefore, the amount of ice in the cone is approximately
Conclusion:
Therefore, the amount of ice in the cone is approximately
(b)
To find: the time required to melt
(b)

Answer to Problem 17PPS
Here
Explanation of Solution
Given:
Theice melts at a rate of 0.1 cubic foot every 5 minutes.
Calculation:
The objective is to find the time required to melt
Use the given rate to find the required time.
Since 0.1 cubic foot of ice melt in 5 minutes, so 1 cubic foot of ice melt in
Thus,
Conclusion:
Thus,
