Answer:
Step-by-step explanation:
Here,
y
∝
x
⇒
y
=
k
x
where k is constant.
⇒
1
=
k
.2
[put y =1,x=2]
⇒
k
=
1
2
Again, y = kx
⇒
y
=
1
2
×
4
[put x = 4]
⇒
Y
=
2
Answer:
y
=
2
Answer: A
Area of square = l * w
L = 22; W = 22
Area of square = 484
Area of circle = pi * r^2
r = 11
Area of circle = 121 pi
Area of shaded region = Area of square 1 area of circle
So… 484 - 121 pi
Answer:
Option B.
Step-by-step explanation:
The given vertices of the polygon are (-6,-2),(-5,1),(-1,4),(1,1),(5,3),(1,-2).
We need to find the area of the polygon.
Plot the given vertices and on a coordinate plane and draw the polygon. Divide the polygon in 4 parts as shown below.
Area of rectangle is

Area of triangle is

Area of each figure is




Area of polygon is


The area of polygon is 34.5 units².
Therefore, the correct option is B.
