An inch of rain implies water one inch deep per surface area. An inch of rain equals 5.61 gallons per yard. An inch of rain equals 27,150 gallons per acre.
That would depend on the size of the lake. One commonly-used measure is "acre-feet", which is the amount of water that would cover an area of one acre, one foot deep. This is equal to 325,851 gallons, which you must admit, is a pretty large number.

4.578 gallons for every inch the water is deep.
Is 42 in inches or feet? I've answered the problem below for inches since that makes more sense for a pool. Volume of pool = area of pool * depth V = pi*r^2 * depth = 3.14*7.5*7.5*3.5 = 618 cubic feet The volume of 1 gallon of water = 0.133680556 cubic feet. Therefore, the # of gallons of water in the pool = 618/0.133680556 = 4623 gallons of water In actually, because of significant digits in the depth and diameter of pool, the answer would be approximately 4600 gallons of water

There are 27,154 gallons of water in one acre of land that is one inch deep.
1 acre = 43560 sq.feet. 1 foot deep water over an acre is 43560 cubic feet, which is 325851.4 gallons in 1 foot deep. If it is 1 inch deep (1/12 foot) then it is 27154.3 gallons in 1 inch deep.
It depends on the depth of the water. Assuming the water in one inch deep, there would be about 13,577 gallons of water in the half acre.
A 1000 acre lake that is 7 feet deep (uniformly) will have 7000 acre feet of water in it. An acre foot is an acre of water one foot deep, and the unit is used to measure reservoir water capacity. The conversion factor is that one acre foot equals about 325,851.5 gallons. The lake in question is holding 7000 times 325,851.5 gallons of water.
1 acre is 6,272,640 square inches. Since you want to cover it one inch deep you need 6,272,640 cubic inches of water. There are 231 cubic inches in a gallon. So divide 6,272,640 by 231 and you get 27,154.2857 gallons! HOWEVER: If you want to save water, consider this: When water freezes, it increases in volume about 9%. So if you used ICE to cover your acre and only needed the ice to be 1 inch deep, you could use 9% less water to start with! (I'll let you do the math on that.) Ice is still water, so unless you are asked to use LIQUID water this question has 2 answers.
The answer will depend on how deep the lake is!
Approximately 8,146,286 gallons of water.
1 acre = 43,560 square feet1 cubic foot = 7.4805 gallonsVolume = (surface area) x (depth) = (43,560) x ( 1 ) = 43,560 cubic feet = 325,851 gallons (rounded)
If the pond is uniformly 6-feet deep it would contain about 1,955,109 gallons of water.
Approximately 977,553 gallons of water.
Approximately 48,878,000 gallons.
