Asked by Sandra

Am I correct?
The radius of a cylinder is 3x – 2 cm. The height of the cylinder is x + 3 cm. What is the surface area of the cylinder? Use the formula A = 2pi r2 + 2 pi rh.
2spi (3x2 + 10x – 8)
2 pi (12x2 + 7x-2)
2 pi (12x2 -2x +13) my answer
2 pi (12x2 -5x -2)
Answered by Steve
a = 2pi r h + 2 pi r^2
= 2pi((3x-2)(x+3) + (3x-2)^2)
= 2pi(3x^2+7x-6 + 9x^2-12x+4)
= 2pi(12x^2-5x-2)
