Aconical pile of road salt has a diameter of 112 feet and a slant height of 65 feet. after a storm, the linear dimensions of the pile are 13 of the original dimensions. a. how does this change affect the volume of the pile? b. during the storm, 350 pounds of road salt was used for every lane mile. estimate the number of lane miles that were covered with salt. round your answer to the nearest hundred lane miles. a cubic foot of road salt weighs about 80 pounds. c.how many lane miles can be covered with the remaining salt? round your answer to the nearest lane mile.

we know that

the volume of a cone is equal to

in this problem

the radius is equal to

1) Find the height of the cone before the storm

Applying the Pythagorean Theorem find the height

2) Find the volume before the storm

3) Find the volume after the storm

After a storm, the linear dimensions of the pile are 1/3 of the original dimensions

so

r=(56/3) ft

h=(33/3)=11 ft

4) Find how this change affect the volume of the pile

Divide the volume after the storm by the volume before the storm

therefore

the answer part a) is

The volume of the pile after the storm is times the original volume

Part b)  Estimate the number of lane miles that were covered with salt

5) Find the amount of salt that was used during the storm

6) Find the pounds of road salt used

7) Find the number of lane miles that were covered with salt

therefore

the answer part b) is

the number of lane miles that were covered with salt is

Part c) How many lane miles can be covered with the remaining salt? Round your answer to the nearest lane mile

the remaining salt is equal to

8) Find the pounds of road salt

9) Find the number of lane miles

therefore

the answer part c) is

the number of lane miles is

250
