Answer:

Step-by-step explanation:

We need to calculate the volume of the solid figure

The figure is made of two shapes:

Conical partHemispherical partStep 1 : Calculate the volume of the conical part:

The following is the formula of calculating the volume of a cone:

1/3 πr²H

Volume = 1/3 × 3.142 × 60 × 60 x 120

= 452448 cm³

Step 2: Calculate the volume of the hemispherical part

Formula for calculating the volume of a hemisphere

2/3πr³

Volume = 2/3 × 3.142 × 60 × 60 × 60

= 452448 cm³

∴ The volume of the solid is:

452448 + 452448 = 904896 cm³

Volume = 904896 cm³

Step 3: Find the volume of the cylinder:

Formula of calculating the volume of a cylinder

πr²H

Volume = 3.142 × 60 × 60 × 180

= 2036016 cm³

⇒The volume of the water remaining in the cylinder will the volume of the solid subtracted from the volume of the cylinder.
