Answer:
what numbers?
Step-by-step explanation:
I think B if not type 1/3 pi 6 squared and add 6.71 or something with the 6.71
The answer is 40 inches. Reason is a^2 + b^2 = c^2. A is 42. B is unknown. C is 58. Taking that information it is 40 inches
The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5
