Question

the curved surface area of a cylindrical rod is 132cm².Find its length. if the diameter is 0.35cm​

Answer 1

Step-by-step explanation:

We have, Curved surface area of cylindrical road =132

cmthe-curved-surface-area-of-a-cylindrical-road-is-132-cm

-find-its-length-if-the-radius-is-35-²

Radius of road = 0.35 cm

Let length of road be ‘h’ cm

By using the formula,

Curved surface area of cylindrical road = 2πrh So, 2πrh = 132 2 × 22/7 × 0.35 × h = 132 h = 132×7 / 2×22×0.35 = 924 / 15.4 = 60cm

∴ Length of road is 60 cm.

Thanks

Answer 2

Answer: The length of the cylindrical rod = 60 cm

Step-by-step explanation:

Curved surface area of cylindrical road =132 cm2

Radius of road = 0.35 cm

Let length of road be ‘h’ cm By using the formula,

Curved surface area of cylindrical road = 2πrh

So, 2πrh = 132

2 × 22/7 × 0.35 × h = 132

h = 132×7 / 2×22×0.35

= 924 / 15.4

= 60cm

∴ Length of road is 60 cm.
