Formula for the area of a circle:
A = πr² [A = area r = radius]
The radius is (half) the diameter. Since the diameter = 10cm, the radius = 5cm.
You know:
r = 5cm Substitute/plug this into the equation
A = πr²
A = π(5)²
A = 25π -> A = 25(3.14)
A = 78.5cm²
F(5) would be 16. because f(1) is only 3.2 so if you multiply 3.2 x 5 you will get 16
Answer:
B
Step-by-step explanation:
This is because when you reflect a triangle the letters need to be the same distance from the point of reflection (the y axis) when you count everything out B is the only answer with all of the correct coordinates.
C) 1/5 th is the correct answer. Slope is rise over run. You go up 1 and then you go to the right 5. Since the line is facing right it is positive.
Answer: the chairs alone would cost $358.36, and since you would already know how much the table costs you would just add it together to get $958.35
