Question

133 The population of a teen increases o amually, of its present pobedalion is 132660 What is it a year ago?​

Answer 1

Step-by-step explanation:

We have,

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.
