The lateral area of a cone is determined with the formula , where c is the
circumference and ℓ is the slant height.So to find the circumference of the cone, solve the formula for c.The circumference of the circular base of a cone is 2πr, where r = radius, so the radius of the
base of the cone is 6.27 . A
Since this question involves compound functions, you can combine them.
So f(g(x)) = −11 when x = 2 and f (g(2)) is one of the choices.This problem can also be solved easily by backsolving.28 . C
With the information provided, you can use the Law of Sines to solve for the unknown.
where b and c represent the lengths of the sides opposite the angles B and C, respectively.
