Answer:
D: 65 km²
Step-by-step explanation:
The formula for area of a hexagon when given the base is
A = (3/2)(√3)b² where b is the length of the base
Here, b is given as 5, plug that in and simplify
A = (3/2)(√3)(5²)
A = (3/2)(√3)(25)
A = (75√3)/2
A ≈ 64.95 ≈ 65
Answer:
81
Step-by-step explanation:
divide 405 by 5 to get the number of rotations per minute.
Answer:
radius = circumference / (2 * PI)
radius = 5.8378033126
Circle Area = PI * radius^2
Circle Area = PI * 5.8378033126^2
Circle Area = PI * 34.0799475167
Circle Area = 107.07 square units
