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:
Step-by-step explanation:
Let the width be W.
14w=(8*10)
14w=80
The width of the frame needs to be at least 5.7 inches.
17-2(6-4)(7-3)-7
17-2(2)(4)-7
17-2(8)-7
17-16-7
1-7
-6
Answer:
third choice
Step-by-step explanation:
That would be the third one. It has to be a closed circle because it includes the sign, ≤ meaning that it also has the number 5 included. The numbers that go to the left of 5 are smaller, too.
