Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: ![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
The radius is 3 inches.
![r=3](https://tex.z-dn.net/?f=r%3D3)
The height is three times the radius.
Multiply the radius by three to get the height.
![h=3*3\\h=9](https://tex.z-dn.net/?f=h%3D3%2A3%5C%5Ch%3D9)
The height is 9 inches.
Use the formula to find the volume.
![\pi (3)^29= \pi (9)9=81\pi](https://tex.z-dn.net/?f=%5Cpi%20%283%29%5E29%3D%20%5Cpi%20%289%299%3D81%5Cpi)
The exact volume is 81
inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
Answer:3 and 1/4 is closer to 3 and 3/5 is closer to 4
Step-by-step explanation: one is closer on the number scale then the other
2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10
At the end of February, 7/10 of the wood was used
30% can also be written as .3, which is easier to use in this case.
To find how many just sat around, multiply the number of people by the percentage of how many just sat around.
1400*.3=420
Answer:
![\large\boxed{\dfrac{1}{3p+15}=\dfrac{1}{3(p+5)}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Cdfrac%7B1%7D%7B3p%2B15%7D%3D%5Cdfrac%7B1%7D%7B3%28p%2B5%29%7D%7D)
Step-by-step explanation:
"one over threep + 15":
![\dfrac{1}{3p+15}=\dfrac{1}{(3)(p)+(3)(5)}=\dfrac{1}{(3)(p+5)}=\dfrac{1}{3(p+5)}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3p%2B15%7D%3D%5Cdfrac%7B1%7D%7B%283%29%28p%29%2B%283%29%285%29%7D%3D%5Cdfrac%7B1%7D%7B%283%29%28p%2B5%29%7D%3D%5Cdfrac%7B1%7D%7B3%28p%2B5%29%7D)
