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
Answer: B
Step-by-step explanation:
Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
Answer:
The salary after all the increment = $62899.0879
Step-by-step explanation:
It is given that starting annual salary = $55183
There is given that there are there are three time increment of 0.6 %
So salary after 0.6% increment of 3 times =
= $56182.2656
After that there is other increment of 1.9 % that is 6 times
So salary after this increment = 
So the salary after all the increment = $62899.0879
