-8 and 4. The product, -8 x 4, would be -32 (just think 8 x 4 = 32, then add the negative sign). The quotient, -8 / 4, would be -2 (just think 8/4 would be 2, then add the negative sign).
Zero.
Anything times zero is zero.
-20 * -10 = 200
200 * -1 = -200
-200 * 0 = 0
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
Speed = distance / time
Speed = ?
Distance = 350km
Time = 5 hours
350km / 5hours = 70
He averages 70km/h
