Answer:
≈ 25 in²
Step-by-step explanation:
The general formula for the area of a circle is:
A=πr²
A = (3.14)(8²)
Since the size of the pizza is 16 inches across, the radius is half of that, or 16÷2 = 8 inches.
A ≈ 201 in²
Since there 8 slices of pizza, you can take the total area and divide by 8:
201 ÷ 8 ≈ 25 in²
Answer:
Step-by-step explanation:
16x^2 + 9 = 25
16x^2 = 16
x^2 = 1
x = 1, -1
Answer: x=-7
Step-by-step explanation:
1. distribute the 2 to (3x-12) >>>> 8x+6x-24=-122
2. add 8x and 6x to get 14x >>>> 14x-24=-122
3. add 24 to both sides>>>> 14x=-98
4. divide 14 by both sides>>>x=-7
