Find the curved surface area of a cylindrical tank of base radius 30 cm and height 2m

37 700m² (rounded off to 3 s.f.)

Step-by-step explanation:

When the curved surface area of a cylindrical tank is laid out, it will be like a rectangular piece of sheet with the circumference of the base circle as its length and the height as its breadth.

Circumference of base circle with radius 30cm = pi × 30 × 2

                                                                              = 60pi

2m = 200cm

Curved surface are = 60pi × 200

                                 = 12 000pi

                                 = 37 700m² (rounded off to 3 s.f.)
