Answer:
The number of trees in each row is 21.
Step-by-step explanation:
Let us assume the number of trees in each row = m
So, the number of rows in the orchard = Number of trees in each row + 10
or, total number of trees in each row = (10 +m)
Now, Total number of Trees = Number of Rows x Number of trees in 1 row
⇒ 651 = m (m + 10)
⇒ (m +31) = 0, or (m-21) = 0
⇒ m= -31, or m = 21
Now, as m = The number of trees in each row, so m ≠ -31
So, m = 21
Hence, the number of trees in each row is m = 21.
Just substitute each number in for the variables: 9 for m and 3 for n.
2m+2n
= 2(9)+2(3)
= 18+6
= 24
The equation for a circle is
(x-h)² + (y-k)² = r²
h = your given x
y = your given k
Let's plug everything in!
(x - 5) ² + (y - (-1)) ² = 12²
Your final equation is
(x - 5) ² + (y + 1) ² = 144

Answer:
B. 785 M
Step-by-step explanation:
Circumference = 2*pi*r
C = 2 * pi * 125
C = 250pi This is the exact answer
Now approximating with pi as 3.14
C = 250 (3.14)
C = 785
