Answer:
1.797 mm
Step-by-step explanation:
The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.
The volume of a cylinder equation is:
V = hπr^2
- We want to find h
- We are given diameter and we will want the radius so we divide
21.17/2 = 10.585
r = 10.585
So to find h we manipulate the equation by dividing both sides by pi and r^2
resulting in the following:
h = ![\frac{V}{\pi r^2}](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B%5Cpi%20r%5E2%7D)
now substitute given values and we get
h =
= 80.883
Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).
Thickness = 80.883/45 = 1.797 mm
Answer:
9 Hours
Step-by-step explanation:
On the first day they drove 5 hours
On the second day they drove 4 hours
5 hours + 4 hours =9 hours
Answer:
- 20 - (3 × 23 - 5) =
- 20 - (69 - 5) =
- 20 - 64 =
- - 44

Answer:
She should order 10 orders of the 4-pizza deal from Peat's Pizza
Step-by-step explanation:
<u>Peat's Pizza deal:</u>
4 x 10 = 40 | 26 x 10 = 260 | so if you choose the Peat's Pizza deal then Tina would have to pay $260.
<u>Pizza Palace deal:</u>
10 x 4 = 40 | 75 x 4 = 300 | so if you choose the Pizza Palace deal then Tina would have to pay $300.
Hope this helps :D
