Question

Find the volume of the following solid:

Answer 1

Answer:

93214.28 cm³

Step-by-step explanation:

The area of the given solid in the front side is = area of the rectangle + area of the semi circle.

= ( 40 × 30 ) + 0.5 × π × r²

= $(40 \times 30) + 0.5 \times \frac{22}{7} \times 15^{2}$ {Since radius = 0.5 × Diameter = 0.5 × 30 = 15 cm}

= 1553.57 cm².

Now the volume of the solid is given by (Area of the vertical surface × horizontal length) = 1553.57 × 60 = 93214.28 cm³ (Answer)
