Help me please with this question

Total surface area of the three tanks is 34.32m^2 and 7 tins of paint

Step-by-step explanation:

Radius = diameter ÷ 2

Surface Area = 2 pi radius height + 2 pi radius^2

=2 (3.14) x 0.7 x 1.9 + 2 (3.14) x 0.7^2

= 11.44m^2

Total Surface Area of 3 Tanks = 11.44m^2 x 3

= 34.32 m^2

If 1 tin of paint covers 5m^2 then 1 tank takes 2

Why = 11.44m^2 / 5

=2.288

Therefore = 3 x 2

= 6

And maybe = 6 + 1

= 7

Because if you devide 34.32m^2 with five you will have a balance of 6.864 So 7
