Answer:
42.1558 km
Step-by-step explanation:
We know that 1 mile = 1,609 km
Then use this data as a conversion factor.
If we want to transform miles to kilometers then our conversion factor should be:
Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers
Answer:
V = π /2 volume units
Step-by-step explanation:
Volume of y = √x bounded by y = x and y = 1
y = √x
limits of integration ( see Annex )
By simple inspection limits of integration are x = 0 to x = 1
or y = √x and y = x
solving these two equations
x = 0 y = 0 x = 1 y = ± 1
V = ∫ π*f(x)²*dx
V = π * ∫₀¹ x*dx = π * x²/2 |₀¹
V = π * (1/2) - 0
V = π /2 volume units
