Deena has a set of 4coasters on her coffee tables and each coaster is shaped like a a cylinder with a height of 0.5 inches and a radius of 2.5 inches. Wich is the total surface area of the 4 coasters?

Suraface Area of cylinder: A=2πrh+2πr^2

A = 2π(2.5)(0.5) + 2π(2.5)^2

Surface Area for each cylinder coaster is ≈47.12.

I'm not sure if they question is asking to combine all 4 cylinders' surface areas but if so, 47.12*4 = 188.48

okay wait before i answer, is this for your points on a graph?

283 square feet
