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
Answer:
6
Step-by-step explanation:
base + 2(legs) = 56 (2 legs are the same because it's isosceles)
x + 2(5x - 5) = 56
x + 10x - 10 = 56
11x -10 = 56
11x = 66
x = 6
