WILL MARK BRAINLIESTWhich expression represents the surface area of the cone?

Answer:Third optionStep-by-step explanation:By observing the diagram we can see that the diameter of circular base is 6 inches. The diameter will be sued to find the radius.r = 6/2 = 3 inchesWe can also see from the diagram that lateral height denoted by l is 5 in.We know that the formula for surface area of a cone is given by:[tex]SA = \pi rl+\pi r^2\\Putting\ the\ values\ of\ r\ and \l\\SA = \pi (3)(5)+\pi (3)^2[/tex]Comparing it with the options we get that the third option is correct ..
