Answer:
The area of the wrestling ring is 5.29π
Step-by-step explanation:
A sumo wrestling ring is circular and has a circumference of 4.6π meters.
To find its area, we need to first find its radius.
The circumference of a circle is given as:
where r = radius
Hence, the radius of the ring will be:
The radius of the ring is 2.3 m.
The area of a circle is given as:
Hence, the area of the wrestling ring (in terms of π) will be:
The area of the wrestling ring is 5.29π
Answer:
0.071
Step-by-step explanation:
Number of wins by Alaskan Malamute = 21
Number of win by Great Pyrenees = 3
Number of wins by Siberian Husky = 18
Total number of shows = 42
We need to calculate the empirical probability that next winner will be a Great Pyrenees.
Empirical probability is defined as the ratio of the number of times a specific event occurs to total number of possibilities of all events being considered. In given case, the event that best of the show was a Great Pyrenees occurred 3 times, and total number of events were 42. So,
Empirical Probability that next winner will be a Great Pyrenees =
Hence, the empirical probability that the next winner of "Best of Show" will be a Great Pyrenees is 0.071
