Question

The circumference of the base of the right circular cylinder is 44cm and height is 10cm.Then lateral surface area is? ​

Answer 1

Answer:

h = 10 cm

circumference of circle = 2πr

44 = 2 ×22 / 7 × r

44 ×7/44 = r

r = 7 cm

lsa of cylinder = 2πrh

= 2 × 22/7 ×7 × 10

= 440 cm^2

Answer 2

Answer:

HERE'S YOUR ANSWER ---

Step-by-step explanation:

GIVEN --

CIRCUMFERENCE OF CIRCULAR CYLINDER - 44cm

THEREFORE --

2πr = 44cm

2 × 22/7 × r = 44

r = 7cm

NOW --

LATERAL SURFACE AREA OF CYLINDER -

2πrh

2 × 22 / 7 × 7 × 10

= 440 cm²...
