1,200 people have spinal injuries from falls.
Answer:
169π
Step-by-step explanation:
circle eq: (x-a)²+(y-b)²=r², where (a,b) is center and r is radius
r²=169
r = ±13
since a radius length must be positive, r = +13, not -13
A of circle: πr²
r = 13
169π
given that the circle eq has r², you could've noticed that you can take the constant in the circle eq and multiply that by π to get the same answer
Given:
The expression is
To find:
The value of the given expression when y=-5.
Solution:
We have,
Putting y=-5, we get
Therefore, the value of the given expression is 50 when y=-5.
