AOB = 2 . x
2x = 60°
x = 30°
Answer:
The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m
The equation would be:
144 x 3.14 - 64 x 3.14 = 251.2
Step-by-step explanation:
First, you need to find out what the whole circle is:
The whole circle is 452.16
Then, find the inner circle :
8 x 8 x 3.14
200.96
Last, subtract the whole by the inner:
452.16 - 200.96 = 251.2
hope this helps!
Answer:
14/50 or 7/25 or 0.28 or 28%
Step-by-step explanation:
The spinner is spun 50 times. (8+6+9+11+9+7=50)
It lands on 1 or 2 a total of 14 times. (8+6=14)
So the experimental probability is 14 out of 50. There are several ways this can be represented. It depends on what your teacher wants. it could be as a fraction or a decimal or a percentage.
14/50 or 7/25 or 0.28 or 28%
