Answer:
Volume (V) = 2522.0 mm^3
Step-by-step explanation:
The volume of cylinder is :
V = π r 2 h
We know that the height (h) is 19.
We also know the radius (r) is 13/2 = 6.5
So,
V = π 6.5^2*19
V = 2522.0 mm^3
Converting 1 hour and 15 minutes to minutes only, its 75 minutes. 75 - 54 is 21. So, Martin has 21 minutes left to finish.
I believe the answer would be -6
Answer:
B (3x / ( 5pi)) ^ 1/3 = r
Step-by-step explanation:
x=5/3 pi r ^3
Multiply each side by 3/5
3/5 x= pi r ^3
Divide each side by pi
3x / ( 5pi) = pi r^3 /pi
3x / ( 5pi) = r^3
Take the cube root of each side
(3x / ( 5pi)) ^ 1/3 = r^3 ^ 1/3
(3x / ( 5pi)) ^ 1/3 = r
The ramp is simply a right triangle when viewed from the side. The rise is the height of the triangle and the run is the length or base. The slope of the ramp is the angle that the ramp makes with the ground. Plug those values into the formula for tanФ = opposite/adjacent or rise/run and solve for Ф. You should end up with 0.23
