The answer is the first one or -10
Answer:
(x-2)²+(y+3)²=9
Step-by-step explanation:
We know that the formula for the area of the circle is:
(x-h)²+(y-k)²=r²
-h,k being the center coordinates
-r being the radius
In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:
(x-2)²+(y+3)²=9
Answer:
So Age of the person is 9.286 years who used 65 trees
Step-by-step explanation:
Given :
Trees used per year = 7 trees / year
Person Used = 65 trees in life
To Find:
Age of person=?
