Answer:
≈ 20.11 m²
Step-by-step explanation:
Area of lawn covered by one full rotation:
- Ch = πdw, where
- C= circumference of the roller,
- w = width of the roller,
- d = diameter of the roller
<u>Area covered by 20 rotations of the roller:</u>
- 20*πdw = 20π*0.4*0.8 ≈ 20.11 m²
None of the answers in my opinion is correct This is because if we try solving this expression we obviously first have to apply bodmas rule which states that brackets should be solved firstly and then division, multiplication, addition and then subtraction.
So if we apply bodmas here we will first do 82 / 22 which come out to be 3.72 and then we will add 22 to 3.72 which becomes more than 20 obviously which is the largest options in the answer. Hence all options are incorrect.
