Answer:

Step-by-step explanation:

Circumference of base = 44cm

And base of cylinder is a circle

2πr=44

πr=44/2

22/7×r=22

r=7cm

Height of cylinder=10cm

Lateral surface area of cylinder=2πrh

=2×22/7×7×10

=440cm²

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
