Question

If the height of a cylinder is 50 cm and the area of ​​curvature is 550 cm2, find its diameter.​

Answer 1

C.S.A of Cylinder=550

2πrh=550

=>2×22/7×r×50=550

=>r=550/50×7/2×22

=>r=7/4cm

Diameter=7/4×2=14/8cm

Answer 2

ANSWER:

Curvature =500 cm²

2πrh =550

~ 2 x 22/7 x r x 50 =550

~ r =550/50 x 7/2 x 22

~ r =7/4 cm

Diameter =7/4 x 2

=14/8 cm
