If a cylindrical vessel is 12 cm long and its surface area is 540 cm2, set up an equation to find its radius.

Option (1)

Step-by-step explanation:

Surface area of a cylindrical vessel is given by the expression,

Surface area =

                     =

Here, r = Radius of the vessel

h = Length of the vessel

By substituting the values of 'h' and surface area in the expression,

2πr(12 + h) = 540

Therefore, Option (1) will be the correct option.

560

hope this : )

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
