How do i find this? i keep getting 31, but it should be 30

Your calculation for the cylinder volume is 31,792.50 cubic feet
I calculate it as 31,808.63 cubic feet
So, the 10,000 cubic feet mark would be located at
(10,000 / 31,808.63) * 45 feet =
0.3143800912 * 45 =
14.147104104 from the bottom
45 - 14.147104104  =
30.852895896  from the top
and that rounds to 31 feet
I get the same answer as you.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
