Answer:
Step-by-step explanation:
2. Solution = (Cylinder) V = πr²h
V = 3.14 x 1.15 x 1.15 x 8
V = 3.14 x 1.3225 x 8
V = 3.14 x 10.58
V = 33.2212 cm
3. Solution = (cone) V = ⅓ π²h
V = ⅓ (3.14 x 4 x 4 x 3)
V = ⅓ (3.14 x 16)
V = ⅓ (150.72)
V = 50.24 cm
Hope this helps ! (please mark me as the brainliest.) ^^

Answer:
1. V = R × H
= 2.3 × 8
= 18.4 cu.cm
2. V = R × H
= 4 × 3
= 12 cu.cm
