@Vocaloid @dude @Shadow
A cylinder is basically a rectangle wrapped around two circles. Solve for the area of the circle. Multiply it by two. You got the two circles. Next solve for the circumference of the circle. Multiply it by the height of the cylinder. You got your 'rectangle'
@bm717 Does that sound about right Ms. Calculus?
Yes @shadow, you got it right for once (:
Can you plug in the numbers and I will solve it?
@Shadow is a little too noob to do that.
\[A _{c} = \pi r^2\] \[C = 2 \pi r\] \[A _{r} = C \times h\]
Ac = area of the circle Ar = Area of the 'rectangle' Add them all up and you're done
From my calculations, I got D...am i correct?
Awe, look at @shadow, reading Yahoo Answers, @Nicole Isn't he so adorable?
?
LMAO...is this actually from yahoo?
No she is just salty
Ohh...ight so am I right? XD
I got it as well. Good job :)
\[A = 2(\pi \times 30^2) + (2 \pi \times 30) \times 19\]
\Yes
\[A = 2940 \pi\]
Different question please (:
sure
