Answer:
1,005cm²
Step-by-step explanation:
First, you need to know the area of a cylinder and also the value of pi.
Area = 2πrh
pi = π = 3.14
r = radius = 80cm
h = height of cylinder = 20
now let's substitute
[tex]2 \times 3.14 \times 80 \times 20 = 1004.9{cm}^{2} [/tex]
but to the nearest square centimetre is.
1005cm²
because the number after the point is more than 4 so we add one to the last number before the point.
