Question

a can of soup 15 cm high and it's base has a diameter of 7 cm. how much paper is needed to make the table on the can.

Answer 1

Given height = 15cm and diameter = 7cm. radius = d/2 = 3.5

Curved Surface Area = 2pirh

                                    = 2(22/7)(3.5)(15)

                                    = 330 sq.cm.


Hope this helps!

Answer 2

Hey!

Given,
Height(h) = 15 cm
Diameter(d) = 7 cm

Now Radius = d/2
                    = 3.5 cm

We know,
C.S.A = 2πrh
          = 2*22/7*3.5*15
          = 330 cm²

Hope It Helps You!
