2 to 1, 4 to 2,  10 to 5 , 20 to 10 , 80 to 40.

Step-by-step explanation:

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.

this is answer of 144 cubic meters
