Answer:
18 π cm^2.
Step-by-step explanation:
The area of the whole circle = π r^2 = 81π cm^2.
Since there are 360 degrees in a circle the area of the shaded region =
80/360 * area of the circle.
This = 80/360 * 81 π
= 2/9 * 81 π
= 18 π

Answer:
x=3
y=4/3
Step-by-step explanation:
Substitution Method:
Substitute the value of x into the equation
2(6y-5)-3y=2
Solve for y
12y - 10 - 3y= 2
12y - 3y=2 +10
9y=12
y=12/9
y=4/3
Substitute the value of y into the other equation
x=6×(4/3) - 5
Solve for x
x=8-5
x=3
