Question

LSA of cylinder whose circumference is 44cm and height is 11cm is

Answer 1

C = 2πr = 44cm
2*22/7*r = 44
r= 44*7/44
r = 7 cm
LSA = πrl
=22/7×7×11
=242cm^2

Answer 2

Answer:

1)1540 cm³ = volume.

2) 440 cm² = lateral surface area of cylinder.

Step-by-step explanation:

44 cm is the circumference.

10 cm is height of cylinder.

2πr is circumference base of circular.

= 2πr = 44

= 2 × 22 / 7 × r = 44

= 44r = 44 × 7

= R = 7 cm

πr²h = volume of cylinder

= 22 / 7 × ( 7 )² × 10

= 22 / 7 × 7 × 7 × 10

= 22 × 7 × 10

= 1540 cm³

2πrh = lateral surface area

= 22 × 22 / 7 × 7 × 10

= 2 × 22 / 7 × 10

= 2 × 22 × 10

= 440 cm²
