If f(x) = (30x - 2), find f(3)

If we’re asked for f(3), we will place 3 instead of x

30×3=90

So,

90-2=88

f(x)=88

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
