Question

The inner diameter of a circular well is 7m. It is 15m deep. Find its inner cirved surface area​

Answer 1

given :

radius =7/2

height =15

curved surface area of cylinder =2πrh

=2×22/7×7/2×15

=330 m^2

hope this will help you

Answer 2

Answer:

330 m sq

Step-by-step explanation:

Diameter=7 m, height= 15 m

radius=7/2

formula = 2Лrh

Now, Inner curved surface area=2Лrh

                                                    =2 x 22/7 x 7/2 x 15

                                                    =330 m sq
