Answer:
Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula 
where r is radius of base of cylinder, h is the height
Volume of a cone is given by 
where r is the radius of base of cone, h is the height
The radius of the cylinder = 
(diameter) = (12) = 6cm
Height of cylinder = 15cm
Volume of cylinder 
Radius of cone = (radius of cylinder) = (6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone, 
Difference is the volume of the remaining solid
Answer: Irrational
Step-by-step explanation:
It is irrational because you cannot multiply a number by the same number to get the square root of 2.
I think the approximation is 1.4 or 1.42
Answer:
1. 20
2. 23
3. 6
Step-by-step explanation:
We have that:
f(x) = 2x
g(x) = x² + 1
f(g(x)) is the composite function of f and g. So
f(g(x)) = f(x²-1) = 2(x²+1) = 2x² + 2
1. f(g(3))
f(g(x)) = 2x² - 2 = 2(3)² + 2 = 18 + 2 = 20
2. f(3)+g(4)
f(3) = 2(3) = 6
g(4) = 4² + 1 = 17
f(3) + g(4) = 6 + 17 = 23
3. f(5) - 2g(1)
f(5) = 2(5) = 10
g(1) = (1)² + 1 = 2
f(5) - 2g(1) = 10 - 2*2 = 10 - 4 = 6
21.99 or 22 days
you just take 1900000 divided by 86400 and you get 21.99 or 22 days to spend the money
