Answer:
h = 5.705m
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
V = 363 cubic meters
d = 9m
h = ?m
d = 2r
d - diameter
r - radius
r = d/2
r = 9/2
π- 3.142
Insert the values into the formula of volume of cylinder
V = πr^2h
363 = 3.142 * (9/2)^2 * h
363 = 3.142 * 81/4 * h
363 = 63.6255h
Divide both sides by 63.6255 to get the value of h
363/63.6255 = 63.6255h/63.6255
5.705 = h
h = 5.705m
The variance of a constant is zero. Rule 2. Adding a constant value, c, to a random variable does not change the variance, because the expectation (mean) increases by the same amount. ... Multiplying a random variable by a constant increases the variance by the square of the constant.
