The radius of a cylindrical gift box is (2xplus3) inches. the height of the gift box is three times the radius. what is the surface area of the cylinder? write your answer as a polynomial in standard form. the surface area of the cylinder is nothing.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
