To find the volume of a cylinder, the equation used is V = 3.14r^2h
r = 4, and h = 3, so we input both numbers to get V = 3.14*4^2*3
V = 3.14*4^2*3 = 3.14*16*3 = 3.14*48=150.72
V = 150.7 ft^3
Answer:
B
Step-by-step explanation:
the sum of the roots = - 
x² + 6x - 55 = 0
with a = 1 , b = 6 , then
sum of roots = - 
= - 6
After conducting some mathematical operations, we know that the 3 friends will get $28 back in change from a $100 bill.

What are mathematical operations?</h3>
- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.
So, the change they will get back from $100:
The Coaster is $4.50:
4.50 × 3 (friends) = 13.5
13.5 × 2 (Twice) = $27
The Slide $4.00:
4.00 × 3 (friends) = 12
12 × 2 (Twice) = $24
The Drop $3.50:
3.50 × 3 (friends) = 10.5
10.5 × 2 (Twice) = $21
Change:
100 - (27 + 24 + 21)
100 - 72
$28
Therefore, after conducting some mathematical operations, we know that the 3 friends will get $28 back in change from a $100 bill.
