Answer:
x = 7
Step-by-step explanation:
Distribute the 2 on the right and the -1 on the left: 13 - 2x - 2 = 2x + 4 + 3x
Combine like terms on each side of the equation: 11 - 2x = 5x + 4
Add 2x to both sides, and subtract 4 from each side: 7 = 7x
Divide both sides by 7: x = 7
Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286
