A cylinder closed tin of radius r cm is made from 600cm2 tin sheet of metal.

Zarrin [17]

Answer:

Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π $r^{2}$ )/πr to be the equation for height.

Step-by-step explanation:

The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π $r^{2}$ , for a total of 2π $r^{2}$ . The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.

The total surace area of a closed cylinder is therefore 2π $r^{2}$ + 2πrh.

2π $r^{2}$ + 2πrh = 600

π $r^{2}$ + πrh = 300

πrh = 300 - π $r^{2}$

h = (300 - π $r^{2}$ )/πr

Let f:a to b be a surjective map of sets prove that the relation a if and only if f(a) = f(b) is an equivalence relation whose e

MrRa [10]

Answer:

Step-by-step explanation:

Denote this equivalence relation by $"\sim"$ (i.e, $a\sim b$ if and only if $f(a)=f(b)$ ), is clear that $a\sim a$ is an equivalence relation since $"="$ is. Now, by definition we have that $[a]=\{b\sim a \mid f(a)=f(b) \}=f^{-1}(a)$ .
