Step-by-step explanation:
The center of a circle with 2 end points of a di diameter is the midpoint of the two endpoints.
The formula needed to find the minpoints is
(x,y) = (x2 + x1)/2, (y2 + y1)/2
x2 = 3
x1 = 3
y2 = 0
y1 = -7
midpoint = (3 + 3)/2, (0 - 7)/2
midp[oint = 3,-3.5
The midpoint is the center of the circle. Observe that the signs get changed when entering the values for (x,y)
So far what you have is (x - 3)^2 + (y + 3.5)^2 = r^2
To determine r^2 you need only take the distance from the center to oneof the endpoints.
r^2 = (3 - 3)^2 + (3.5 - 0)^2
r^2 = 3.5^2
r^2 = 12.25
Answer: (x - 3)^2 + (y + 3.5)^2 = 12.25
Answer:
9x+27
Step-by-step explanation:
3x(4−1)+6+21
=9x+6+21
Combine Like Terms
=9x+6+21
=(9x)+(6+21)
=9x+27
Answer:
For covering 
unit area of the entire playground, the amount of sand required is equal to volume of 
buckets of sand.
Step-by-step explanation:
Given -
volume of sand in bucket is able to cover 
area of the entire playground
Thus,
For covering unit area of the entire playground, the amount of sand required is equal to of the total volume of sand in bucket
For covering unit area of the entire playground, the amount of sand required is equal to
For covering unit area of the entire playground, the amount of sand required is equal to volume of buckets of sand.
