Question

URGENT,HOW TO FIND SURFACE AREA FOR A CYLINDER AND CONE?

Answer 1

SA of a cylinder is 2*pi*r^2*h where r is the radius and h is the height

SA of a cone is (1/2)*pi*r^2*h where r is the radius and h is the height.

Answer 2

can someone find the surface are for this cone and simplify how they got it?

Answer 3

i meant cyliner

Answer 4

I gave you the equations above. Your radius is 3 and your height is 4.

Oh. Shoot. There's a typo in those formulas from earlier.

So just plug those values into the surface area formula

SA = 2*pi*r^2 + 2*pi*r*h

which equals

2*pi*3^2 + 2*pi*3*4

Answer 5

is the answer 131.8 units squared?

Answer 6

thanks
