Answer:
799
Step-by-step explanation:
Volume of a cylinder = pi x radius^2 x height of cylinder and diameter/2 is the radius so...
3.14 x (8.4/2) ^ 2 x 10 = 553.9
Since there is a hole that means you have to find the volume of the hole and subtract that from the volume of the whole pipe (553.9)
3.14 x (6/2) ^2 x 10 = 282.6
553.9 - 282.6 = 271.3
Here is the formula:
d=C/

Dividing fractions is the same as multiplying the reciprocal, but inorder to multiply fractions you need to convert the mixed number to an improper fraction. so .....
Formula for mixed numbers to improper fraction is:
(whole number*denominator)+numerator and you put your answer over the denomiator.
Solving everything
37 5/7 = 264/7
264/7*7/22 (reciprocal of 22/7)=
1848/154=
12
