given that x and y vary inversely then the equation connecting them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 6 when x = 7

k = yx = 6 × 7 = 42

Find the surface area of a cone if the diameter of its base is 13.5 feet, and it has a slant height of 16.8 feet. Round to the n
Tresset [83]

The diameter is given which is 13.5feet and radius is half of diameter. Therefore radius = 6.75 feet.

Slant height = 16.8 feet

The formula of surface area of cone is

S = \pi *r(r+l) \\ S = \pi*6.75(6.75+16.8) \\ S =\pi*6.75*23.55 = 499.2 ft^2

Correct option is C
