# Compute the surface area?

Compute the surface area of the portion of the plane 3x+y+2z=6 inside the cylinder x^2+y^2=4. (Answer: 2pi*sqrt(14)) The formula for the surface area of a cylinder is A=2pi*r^2+2pi*r*h...

# a cylinder has a surface area of 402 cm^2. The height is three times greater than the radius. What is the height of the cylinder?

what i did: 402 = 2πr^2+2πr(3r) how do i separate r?

# suppose the radius and height of a cylinder are both doubled. by how much is the surface area increased, by how much is the volume increased

i dont get how to find the answer
