Question

The inner diameter of a circular well is 7 meter and  it is 10 meter deep. Its inner curved surface area is​(trisha)​

Answer 1

Step-by-step explanation:

Given, diameter of well is 3.5 m and depth is 10 m

Then radius of well =

2

3.5

=1.75 m

And height of well =10 m

Then curved surface area of well = 2πrh

=2×

7

22

×1.75×10

= 2×22×0.25×10

=110 sq. m
