Cone, diameter of base 18 ft slant height 14 ft

207π ft²

Step-by-step explanation:

Given in the question,

diameter of the base  = 18 ft

slant height= 14 ft

radius of the base = 18/2

                              = 9 ft

Formula to calculate the surface area

here l = slant height

        r = radius of the base

plug values in the formula

A = π(9)(14)+π9²

A = 207π ft²

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
