Answer:
C. 380
Step-by-step explanation:
Area of the tabletop = area of a circle
Area of a circle = πr²
radius (r) = ½*diameter = ½*22 = 11 in
Take π as 3.14
Plug in the values into the formula
Area of tabletop = 3.14*11² = 379.94
Area of tabletop would be approximately 380 in² (to nearest whole number)
Answer:
The length of the rope = 8.94 meters
Step-by-step explanation:
∵ The flagpole is 8 meters high
∵ The hook is 4 meters from its base and the hook is in the ground
∵ The flagpole and the ground ⊥ to each other
