Answer:
16 centimeters cubed
Step-by-step explanation:
Volume of cone is equal to 1/3 * pi * r^2 * h
We are using 3.14 for pi so I'm going to rewrite my formula for volume.
V=1/3 * 3.14 * r^2 * h
We are given diameter is 3 but we need the radius. We know the radius is half of the diameter so the radius is 1.5 since that is half of 3.
We are given the height is 7.
V=1/3 * 3.14 * 1.5^2 *7
Put into calculator
V=16.485
The whole number that this is closest to is .... 16
So
The Volume of the cone is approximately 16 centimeters cubed.
Answer:
$69 is the total cost of the bill
Step-by-step explanation:
60(1.15)
60 is the cost of the bill, and the 1.15 is the added tax plus the previous $60.
Put 60(1.15) into a calculator and
$69
The new price is 69% i think
Simplifying
5n + 3 = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n
Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n
Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4
Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
