Step-by-step explanation:

Answer 2

Given :

• Height = 60cm
• Radius = 10.5cm
• Weight per cm³ = density = 5 g/cm³

To find :

• Weight of cylinder

Approach to question :

• First of all we need to find volume of cylinder
• Then we will find weight by multiplying volume with density

Formula used :

• Volume of cylinder = π (r²)h
• Weight = volume × density

Solution :

Volume = π × (10.5)² × 60

Volume = (22/7) × 110.25 × 60

Volume = 22× 15.75 × 60

Volume = 20790 cm³

weight = volume × density

Weight = 20790 × 5

Weight = 103950grams

weight = 103.95 kg

ANSWER : Weight = 103.95 kg
