Pie is always 3.14 so to find pie you multiply Pie Multiplied by a Total
So-...
3.14π × 23.9817= 236.5699
Answer:1,920
Step-by-step explanation: 4 percent of 2,000 is 80 so subtract the 80 from 2,000 to get 1,920
Answer:
D. NM=12; mK=70°
Step-by-step explanation:
KN≈KM so they have the same 55° and then
180°-55°-55°=70° and
6*2=12
Answer:
x and 2x+1
Step-by-step explanation:
Answer:
V = πr²h
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
where V is the volume, r is the radius, and h is the height of the cylinder.
_____
<em>Comment on the formula</em>
This is a specific version of the formula for any sort of "prism" with parallel bases and a uniform cross section (parallel to the bases). The volume of such a figure is computed as ...
V = Bh
where B is the area of the base and h is the perpendicular distance between the parallel bases. Here, the base is a circle, so has area formula ...
B = πr²
Filling this into the volume formula gives ...
V = πr²h . . . . . as above
