Answer:
27.73 square centimeters
Step-by-step explanation:
<em>Assume the shaded region is the area outside the circle but inside the rectangle.</em>
<em />
Now, we need to find the area of rectangle and area of circle. Then we will subtract area of circle from area of rectangle to get our desired answer.
Area of Rectangle = length * width
Area of Rectangle = 8 * 7 = 56
Area of circle is given by the formula:
Area = 
Where r is the radius, which is 3
So,
Area of Circle = 
Thus, area of the shaded region is:
Area of Shaded Region = 56 - 28.27 = 27.73 square centimeters
X= 2 , y= -3
You have to multiply the second equation by a negative and the you'll get, -3x-y=-3. the y's cancel out and then you combine the x's and the 5 and the 3 and then x=2 and then you pick one of the two equations and sub in the x and solve for y.
Answer:
I think its a. (-2,-4)
Step-by-step explanation:
Answer:
AB = 35
Step-by-step explanation:
For the value of variable z....;
;Perimetre = 132
; 132 = 2(4z + 3) + 2(5z)
; 132 = 8z + 6 + 10z
; 132 - 6 = 8z + 10z
; 126 = 18z
;the value of...z = 7
Therefore the value of length AB;
AB = 5z...then substitute the value of z into the length of AB
; AB = 5(7)
;AB = 35
