Question

Find the area of curved surface if circumference of base of cylindrical tank is 176 square cm and height is 30 cm.

Answer 1

Answer:

5278.968 cm²

Step-by-step explanation:

We have,

Circumference of base = 176 cm

Height of Cylindrical tank = 30 cm

We know,

Circumference of base = 2πr

                                176 = 2 x 3.14 x r

                      176/ 6.28 = r

∴                                     r = 28.02 cm

Now,

C.S.A. of cylindrical tank = 2πrh

                                        = 2 x 3.14 x 28.02 x  30

                                        = 5278.968 cm²
