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: -4x(4x - 15)
Step-by-step explanation:
f(x) = 
+ 60x
y = + 60x
=> - (
- 60x)
=> -4x(4x - 15)
You add the whole numbers together first and then you do the numerators then the denominators. Like for example, #2 would be 2 and then 4 on the top and 6 on the bottom since they share a common denominator! Hoped this helps.
