Answer:
If the diameter is 18 then the radius r=9 so the area is:
πr2=81π≅254.469
Step-by-step explanation:
Explanation:
The area of a circle is given by the formula πr2 where r is the radius.
Answer:
So I (3,0) becomes I' (1,3)
H (5,2) H' (1,1)
G (2,4) G' (2,1)
Step-by-step explanation:
So let's start with I, just count how many times you move to the left then how many times you move up.

Answer:
at x= 0 and x= 1 and not at x= 3.
Step-by-step explanation:
We have the functions, 
and 
.
It is given that,
At x=0, x=1, and x=3,
i.e. 
i.e. 
i.e. 
i.e. x= 0 and (x-1)= 0
i.e. x= 0 and x= 1.
Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).
Thus, we get that at x= 0 and x= 1 and not at x= 3.
Let the three numbers be x, y and z. Then x+y+z=75.
z = 2x. y = x - 9.
Eliminate y and z by substitution: x + (x - 9) + (2x) = 75
Then 4x = 75 + 9, or 4x = 84. x = 21, y = 21 - 9 = 12, and z = 2(21) = 42.
Check: Do 21, 12 and 42 add up to 75?
9/4 + 3/4 = 12/4 divide by 4 and the answer is 1/3.
