Answer:
62
Step-by-step explanation:
The enclosing rectangle is 24 units long and 12 units high. Its area is ...
(24 units)(12 units) = 288 square units
The white circles obviously cover more than half the area, so the only viable answer choice is 62.

If you want to go to the trouble to actually figure it out, you can find the area of each circle using the area formula ...
A = πr² = (3.14)(6²) = 113.04
Then both circles have an area of 2×113.04 = 226.08, and the shaded area is the difference between that and the rectangle area:
shaded area = 288 -226.08 = 61.92 ≈ 62
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:
y = 15x + 30
Step-by-step explanation:
The $30 rental fee is a flat fee.
The $15 per day can be noted as 15x.
y = 15x + 30
10. 50 is roughly around ~16% of 300. (16% is 50.1)
11. 35% of 150 would be 52.5
12. 80 is 200% of 40
