Answer:
z + 12 = 9
Reorder the terms:
12 + z = 9
Solving
12 + z = 9
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + z = 9 + -12
Combine like terms: 12 + -12 = 0
0 + z = 9 + -12
z = 9 + -12
Combine like terms: 9 + -12 = -3
z = -3
Simplifying
z = -3

Answer:
97 cm²
Step-by-step explanation:
The complete question is attached.
The circle has a diameter of 12 m. The radius of the circle = diameter/2 = 12/2 = 6 cm.
The area of the circle = πr² = π × 6² = 113 cm²
To find the area of the shaded portion we have to find the area of sector and subtract it from the circle area.
The angle of the sector (θ) = 360 - 310 = 50°

Area of shaded portion = Area of circle - Area of of sector = 113 - 16 = 97 cm²
