Answer:
125.6 cubic meters
Step-by-step explanation:
To calculate the volume of the cylinder, we will do it as follows:
Vc = Base area * Height
We know that the base of the cylinder is a circle, therefore:
Base area: pi * r ^ 2
replacing we have:
Vc = pi * (r ^ 2) * h
We have r = 2 and h = 10, we replace:
Vc = pi * (2 ^ 2) * 10
Vc = 40 * pi
pi = 3.14
Vc = 40 * 3.14
Vc = 125.6
Which means that the volume of the cylinder is 125.6 cubic meters

Answer:
The time to complete the job is given by the expression below:
Where T = time it takes to wash all the windows
x = the number of workers assigned to the job
Step-by-step explanation:
The proportionality can be represented below as:
T ∝
T = -------------------- Equation 1
Where K is the constant of proportionality
Considering the given instance,
When T = 6, x = 4
6 =
K = 4 × 6
K = 24
Substituting the value of K into Equation 1,
T =
Answer:
56
Step-by-step explanation:
First, I drew picture of a line containing points W and Z.
Next, I added a midpoint between W and Z and labelled it Y.
Next, I added a midpoint between W and Y and labelled it X.
It is given that XY = 14, so that means WX is also 14 (because X is the midpoint, these two distances have to the be the same)
Now I know WY is 28, which means YZ is also 28.
So WZ has to be 56.
