If you meant a thickness of 1/2 inch. . .
Because the inserts are put on all the sides, the dimensions of the usable space are 5 X 5 X 9.  This means the diameter of the base is 5.  The radius is half the diameter, so we divide 5 by 2 to get the radius.  5/2 = 2.5.  Now, we plug in the radius and the height (9) into the formula for the volume of a cylinder, which is volume= \pi  r^{2} h

v= \pi  2.5^{2} *9=176.6 inches^{3}

So, D is correct.

Seth drinks a glass of orange juice every day that contains 0.6 grams of Vitamin C. He eats a serving of strawberries for snack
belka [17]

Answer:

3 week or 21 days consume Vitamin C = 19.95 grams

Step-by-step explanation:

given data

orange juice Vitamin C = 0.6 grams

strawberries Vitamin C = 0.35 grams

to find out

How many grams of Vitamin C does Seth consume in 3 weeks

solution

we first find total Vitamin C consume in 1 day that is

total Vitamin C consume in 1 day = orange juice Vitamin C  + strawberries Vitamin C

total Vitamin C consume in 1 day  = 0.6  + 0.35

total Vitamin C consume in 1 day  = 0.95 grams

so

in 3 week have 3 × 7 = 21 days

so in 21 days consume Vitamin C = 1 day consume × no of days consume

21 days consume Vitamin C = 0.95 × 21

21 days consume Vitamin C = 19.95 grams
