The total volume of the three cylinders is given by:
 V = (3) * (pi) * (r ^ 2) * (d)
 Where,
 r: cylinder radius
 d: cylinder depth
 Substituting values we have:
 V = (3) * (3.14) * (4 ^ 2) * (7)
 V = 1055.04 feet ^ 3
 Answer:
 the volume of oil needed is:
 V = 1055.04 feet ^ 3

Common core question please help!!!
Maru [420]
She has 648 shirts.

Work:
Lisa has 42 pineapples. 4 + 2 = 6
Johnny has 6 marbles.
42 + 4 + 2 + 6 = 54
54 + 5 + 4 = 63
63 + 6 + 3 = 72
But 72 is a multiple of 6!
Let's go further:
72 * 6 = 432

Now let's look at the word 'shirt'.
The middle letter is I.
I is the 9th letter of the alphabet.
Remember the number 72?
72*9 = 648

Over her 17 day winter break, Lindsay want to read the last book in the Harry Potter seriees, which has 759 pages. If she reads
Alex Ar [27]

Answer: Yes, she will finish before winter break is over.

Explanation:

Since we have given that

Number of days in winter break = 17

Number of pages she read in each day = 75

Number of pages in the Harry Potter series she wants to read = 759

Now, we'll use unitary method,

in 1 day , she read = 75 pages

in 17 days , she read is given by

17\times 75=1275\text{ pages}

and 759 pages is less than 1275 pages.

So, she will finish before winter break is over.
