The average height of the fence is 2 m; its length is 20π m. So, its 2-sided area is
A = 2*(2 m)*(20π m) = 80π m² ≈ 251 m²
At 1 L/(100 m²), it will take 2.51 L of paint to paint both sides.
Step-by-step explanation:
I'm not sure what you mean by 'written method' but the sum is 2,654.
I don’t know so sorry maybe ask someone else but just go back to the passage and see if you can find it
