The formula for surface area of a cone = 2pi rh
the radius of the base = 12inches
by the pythagoras theorem, 400 - 144 = 256 =16^2
therefore the height of the cone = 16inches
the surface area of the cone= 16 × 24pi
=384pi inches

Answer:
(B) -9
Step-by-step explanation:
g(x) = 2x² - 11x
To find g(1), we substitute x = 1 into g(x).
g(x) = 2x² - 11x
g(1) = 2(1)² - 11(1) = 2 - 11 = -9
