F = 3/r.
The formula for the volume of a cylinder is
V=πr²h. We know that h=2r, so this gives us:
V = πr²(2r) = 2πr³
The surface area of a cylinder is the sum of the areas of all of the faces. The bottom and top are circles, whose areas are both given by A=πr². The lateral area of a cylinder is given by the circumference multiplied by the height. C = 2πr, and the height is 2r, so the lateral area would be
A=(2πr)(2r)= 4πr². This gives us a total surface area of
SA = 4πr²+πr²+πr² = 6πr².
The ratio of surface area to volume would be:
SA/V = 6πr²/2πr³. After simplifying, we have f=3/r.
Answer:
Only:
B. x=7
D. x=0
Step-by-step explanation:
Substitute the answers in the formula and only 7 and 0 will work.
Answer:
Would 50 divided by 40 work?
Step-by-step explanation:
Since the highest power is nine, it will have ends going in opposite directions.
As x approaches infinity, y approaches infinity
As x approaches negative infinity, y approaches negative infinity
Answer: = 32
Step-by-step explanation:
40 x 80 / 100 = 32
