Answer:
V = 402.12385mm
Step-by-step explanation:
When the diameter is 8mm, the radius is 4mm.
V = (π(4^2))8
V = (16π)8
V = (50.2654)8
V = 402.12385
V ≈ 402, 402.1, 402.12, 402.124
Answer:
(3, 6)
Step-by-step explanation:
You add the x points together and divide by two, then you add the y points together and divide by 2.
For this case we have the following situation:
The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
So we have to define variables:
x: number of months
y: total cost
The mathematical expression that models the problem is:
(x,y) ... (X-163, Y+125) Which ever direction it is, you apply it to the rule.
3(x - 1) = 2x + 9
3x - 3 = 2x + 9
3x (-2x) -3 (+3) = 2x (-2x) + 9 (+9)
(3x -2x) = (9 + 9)
(x) = (18)
x = 18
x = 18 is your answer
hope this helps
