Answer 2

Given :-

• Radius of cylinder = 14 cm
• Height of cylinder = 30 cm

To Find :-

• Curved Surface Area = ?

Solution :-

Let Radius of cylinder be 'r' and Height be 'h'.

★According to Question :-

→ CSA of cylinder = 2πrh

→ CSA of cylinder = 2 × 22/7 × 14 × 30

→ CSA of cylinder = 2 × 22 × 2 × 30

→ CSA of cylinder = 44 × 60

→ CSA of cylinder = 2640 cm²

Hence, Curved Surface Area of cylinder is 2640 cm².

Extra Shots :-

• Volume of cylinder = πr²h
• T.S.A of cylinder = 2πrh + 2πr²
• Volume of cone = ⅓ πr²h
• C.S.A of cone = πrl
• T.S.A of cone = πrl + πr²
• Volume of cuboid = l × b × h
• C.S.A of cuboid = 2(l + b)h
• T.S.A of cuboid = 2(lb + bh + lh)
• C.S.A of cube = 4a²
• T.S.A of cube = 6a²
• Volume of cube = a³
• Volume of sphere = 4/3πr³
• Surface area of sphere = 4πr²
• Volume of hemisphere = ⅔ πr³
• C.S.A of hemisphere = 2πr²
• T.S.A of hemisphere = 3πr²
