Answer:

171 cm³

Explanation:

The object is composed of a cone and a cylinder.

Volume of the object = volume of cone + volume of cylinder

✔️Volume of Cone = ⅓πr²h

r = ½ of 6 = 3 cm

π = 3

h = 5 cm

Volume of cone = ⅓×3×3²×5

Volume of cone = 45 cm³

✔️Volume of cylinder = πr²h

π = 3

r = ½ of 6 = 3 cm

h = 14 cm

Volume of cylinder = 3×3×14

Volume of cylinder = 126 cm³

✔️Volume of the object = 45 + 126 = 171 cm³
