Step-by-step explanation:
the formula for radius is

so. 500 divided by pi times 10. then square root your final answer. cool. let's get started.
3.14*10 is 31.4, you can do that without thinking.
500/31.4=15.92
15.92= 3.99, or just 4
the radius is four.
1.5 cups per day...7 days per week....1.5 * 7 = 10.5 cups per week
16 cups = 1 gallon
16/1 = 10.5/x....16 cups to 1 gal = 10.5 cups to x gal
cross multiply
(16)(x) = (1)(10.5)
16x = 10.5
x = 10.5/16
x = 0.65625 rounds to 0.66 gallons per week
