Answer:
Step-by-step explanation:
the volume of a cylinder is given by:
where r is the radius and h is the height.
and the surface area:
the first term is the area of the circles and the second term is the area of the body.
since "The number of volume of a cylinder is half of its number of the total surface area." we will have that:
substitutig the equivalent expressions on each side:
and we simplify and solve for the height (since is the value we don't know of the cylinder):
we substitute the value of the radius , and we get:
thus the volume is:

Answer:
3000
Step-by-step explanation:
Convert them into numbers: 607 + 2393 = 3000.
Week #1 : 12 hours
Week #2 : 480/60 = 8 hours
Week #3 : 6.5 hours
Week #4 : 750/60 = 12.5 hours
total = 39 hours for all four weeks
