≈ 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

Answer is D
Part A:
Given that the <span>cable runs from the top of a building to a point on the ground 60.3 feet from the base of the building and that the </span>cable makes and angle of 33.7˚ with the ground.
Let the height of the building be h, then
Part B:
Given that the cable runs from the top of a building to a point on the ground 60.3 feet from the base of the building and that the cable makes and angle of 33.7˚ with the ground.
Let the length of the building be l, then
