Answer:
247.34 cm^3
Step-by-step explanation:
let radius be r
2/3=r/h
2/3=r/8.1
r=5.4
cone vol = 1/3πr^2h
= 247.34

Answer:
volume of the cone = 247.375944 cc
Step-by-step explanation:
Ratio of the radius of the cone to hight of the cone
2:3
hight = 8.1 cm
then the radius = 8.1 ×2 ÷3 = 5.4 cm
volume of the cone
= 1÷3 × pi r^2 × h
= 1÷3 × 3.142 × 5.4 ×5.4 × 8.1
= 247.375944 cc
