In this unit, you calculated the surface area of solid figures composed of polygons, such as rectangles and triangles. but imagine finding the surface area of a cylinder—a solid figure that has several curved surfaces. a cylinder is made up of two circular bases and a curved (lateral) surface in between. develop a formula for finding the surface area of the outside of a cylinder based on what you know about the circumference of a circle and the areas of circles and rectangles. (hint: think about rolling a rectangular piece of paper into the shape of a cylinder.) discuss your approach and why it works.

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
