So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters

Cross Multiply
0.0075x = 0.48
x = 64 meters
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
24 times 3= 72+4=76+14=90

Known :
r = 6
h = 8
Asked :
V = ...?
Answer :
V = ⅓πr²h
= ⅓ × 3.14 × 6² × 8
= ⅓ × 3.14 × 36 × 8
= 3.14 × 12 × 8
= 301.44 units²
= <u>3</u><u>0</u><u>0</u><u> </u><u>units²</u> (rounded)
So, the volume of the cone is 300 units²
