Question

2. The curved surface area of a cylindrical road is 132 cm? Find its length if the radius is
0.35 cm.
​

Answer 1

Step-by-step explanation:

using curve surface area of cylinder=2πrh

r=0.35cm

curved surface area of cylindrical road=132cm

so ,

132=2×22/7×0.35×h

h=132×7/2×22×0.35

h=8.5714285714

so,

h=8.5 cm approx

Answer 2

Answer:

Curved Surface Area of a cylinder = 2πrh

                                               132      = 2 × 22/7 ×0.35 × l

                                                 132     = 44 × 0.05 × l

                                                    132   = 2.2 l

                             length of the cylinder   = 132/2.2 = 60cm
