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.
Answer:
c
Step-by-step explanation:
because I had a test on these
C = -840
Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840
