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 = 23r+ 2 x rh.

Surface Area of the cylinder is 6x² + 83x - 58 cm²

Step-by-step explanation:

Step 1: Given surface area of the cylinder, A = 23r + 2rh. Here, r = (3x - 2) and h = (x + 3)

⇒ A = 23(3x - 2) + 2(3x - 2)(x + 3)

⇒ A = 69x - 46 + (6x² + 18x - 4x - 12)

⇒ A = 6x² + 83x - 58 cm²

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
