The surface area, S, of a cone with radius r and slant height h is given by the formula S = pi r(h+ r). Find the surface area of a cone with radius r = 3 inches and
slant height h = 7 inches. Give the answer rounded to the nearest one-hundredth
square inch, in?

1010: 3030

is it i think

d. all of the above

step-by-step explanation:

multiply each one by 3.14

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
