Answer:
radius = 4 inches
height = 24 inches
Step-by-step explanation:
The formula of the volume of a cone is:
V = (1/3) * pi * r^2 * h
where V is the volume, r is the radius of the base and h is the height.
We know that the height is 6 times greater than the base radius, so:
h = 6*r
If the volume is 401.92 in3, we can calculate the radius and the height of the cone:
401.92 = (1/3) * 3.14 * r^2 * 6*r
(1/3) * 3.14 * 6 * r^3 = 401.92
r^3 = 401.92 / ((1/3) * 3.14 * 6) = 64
r = 4 inches
h = 6*r = 6*4 = 24 inches.
Answer:
x=7
Step-by-step explanation:
6(x+5)=72
6x+30=72
6x=42
x=7
Answer:
it's 2
Step-by-step explanation:
To solve this, we can use the z statistic. The formula for
z score is given as:
z = (x – u) / s
where x is the actual cost = 4000, u is the mean cost =
5000, and s is the standard deviation = 2000
Solving for z:
z = (4000 – 5000) / 2000
z = - 0.5
<span>Therefore the piano cost is only 0.5 standard deviations
below the average cost.</span>
(-3,-6) is the answer, thank youuuuu
