Find the work (in ft-lb) required to pump all the water out of a cylinder that has a circular base of radius 5 ft and height 300 ft. Use the fact that the weight-density of water is 62.4 lb/ft3. ft-lb Find the work (in ft-lb) required to pump all the water out of the cylinder if the cylinder is only half full.

i think is g(1)=-1.

hope that i can

a

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
