you solve it like an equation.
4x+20<40
4x<20
x<5
so the answer would be anything less than 5, which is A
Answer:

Kkkkkkkkkkkmmmmmmm
h=0.4
Step-by-step explanation:
6.1h=2.44
h=2.44/6.1
4164.69504π
So the volume of a cone is πr^2 * h / 3
r = 15.072 / π
h = 55
15.072 / π squared * π = 227.165184π
227.165184π * 55 / 3 = 4164.69504π
