Answer: the
Step-by-step explanation:
v= 3.14r^2h
3.14 times 3 times 4 = 113.04
Answer:
Area of the sector![=4.01inch^2](https://tex.z-dn.net/?f=%3D4.01inch%5E2)
Step-by-step explanation:
Area of a circle with the given angle and radius is:
= ![\frac{\beta }{360} *\pi *r^2](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cbeta%20%7D%7B360%7D%20%2A%5Cpi%20%2Ar%5E2)
![radius(r)=2 inch\\\\\beta =115](https://tex.z-dn.net/?f=radius%28r%29%3D2%20inch%5C%5C%5C%5C%5Cbeta%20%3D115)
Putting the values in the formula:
![=\frac{115}{360} *(3.14) *(2)^2](https://tex.z-dn.net/?f=%3D%5Cfrac%7B115%7D%7B360%7D%20%2A%283.14%29%20%2A%282%29%5E2)
![=\frac{115}{360}* 3.14*4](https://tex.z-dn.net/?f=%3D%5Cfrac%7B115%7D%7B360%7D%2A%203.14%2A4)
![=\frac{115}{360} *12.56](https://tex.z-dn.net/?f=%3D%5Cfrac%7B115%7D%7B360%7D%20%2A12.56)
![=\frac{23}{72} *12.56](https://tex.z-dn.net/?f=%3D%5Cfrac%7B23%7D%7B72%7D%20%2A12.56)
![=0.319*12.56\\\\=4.01inch^2](https://tex.z-dn.net/?f=%3D0.319%2A12.56%5C%5C%5C%5C%3D4.01inch%5E2)

Answer:
m = -2/1 or just m = -2
Step-by-step explanation:
Answer:
339.24
Step-by-step explanation:
To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2
The radius is half the diameter do r=3
3.14(3)^2 should give you about 28.27.
This is the area of the top and bottom of the cylinder.
Now, do 28.27x10=282.7 to find the height surface area.
282.7+28.27+28.27=Surface area.
SA= about 339.24
