find the radius and height of the cylinder using the surface area and volume provided. since the scale is 2:3, you have to multiply the radius and height by 3/2 and to get the radius and height of the bigger cylinder. Use those values to calculate volume and S.A of the bigger cylinder.

surface area of the given cylinder is 48pi. so 48 pi = 2pi * radius^2+ 2pi radius*height volume is 45pi so 45 = pi*radius^2*height solve the two equations to get radius and height new radius = 3/2 * radius new height = 3/2 * height use the new values to find the volume and surface area of the new bigger cylinder.

sorry it is 45pi = pi*radius^2*height
