Answer:
Volume of the solid is 377 cm³.
Step-by-step explanation:
Volume of the cylinder = 
Here, r = radius of the cylinder
h = Height of the cylinder
By substituting the values in the formula, (r = 4 cm and h = 10 cm)
Volume of the cylinder = 
= 160π
Since one fourth of the cylinder is removed,
Volume of the remaining cylinder = 160π - 
= 160π - 40π
= 120π
= 120(3.14)
= 376.8 cm³
≈ 377 cm³
Volume of the solid is 377 cm³.

Answer:
$9426.50
Step-by-step explanation:
let noel's salary = x, robert's salary = y and john's salary = z
y = x - 512.75 ..........(1)
z = 3y = 3(x - 512.75) = 3x - 1538.25 ...............(2)
x + y + z = 47645.25..........................(3)
substitute for y and z
x + (x - 512.75) + (3x - 1538.25) = 47645.25
x + x - 512.75 + 3x - 1538.25 = 47645.25
5x = 47645.75 + 512.75 + 1538.25
5x = 49696.25
divide both sides by 5
x = 9939.25 ..... noel's salary
to get robert's salary substitute x in equation 1
y = 9939.25 - 512.75 = 9426.50
y = $9426.50..... robert's salary
Answer:
12/20
Step-by-step explanation:
Cos is adjacent over hypotenuse
Sin is opposite over hypotenuse
Tan is opposite over adjacent
In this case, we have cosine so we would take the adjacent (12) over the hypotenuse (20), and that will be used to find the answer
