The advertised size of a pizza is the diameter of the pizza. Which is closest to the area of the crust of a 15-inch pizza?
707 square inches
177 square inches
225 square inches
47 square inches
Since the answers are spread widely apart, all you need is a very general approximation
diameter is 15 inches, so the radius is 7.5, let's say just 7
𝞹 = 3.14159.... , let's just say 3
area = roughly approximately 3(7^2) < 3*50 = or 150
the closest answer to that is 177
the real answer would be 𝞹(7.5)^2 = 176.71..
The answer is 177 because if you do all the math you will see that that is the answer that is closest to the answer that you originally received.
Work:
Diameter of pizza (d): 15in
15/2=7.5
Radius (r): 7.5
Area (A):
A=r^2π ( Let's just say π=3.14)
r^2=7.5x7.5=56.25
A=56.25x3.14=176.625
176.625 is closest to 177, which makes that the answer. I did this process on a math quiz and I got it correct.
47 is the anser becuze I got corect

To find the area of the crust of a 15-inch pizza, we first need to calculate the radius of the pizza. The radius is half of the diameter. Therefore, the radius of the pizza is 15 inches divided by 2, which equals 7.5 inches.
Next, we need to calculate the area of the crust of the pizza. The area of a circle is given by the formula:
Area = π * (radius^2)
Plugging in the value for the radius (7.5 inches), we get:
Area = π * (7.5^2)
Calculating this, we find:
Area ≈ 176.71 square inches
Since the question asks for the closest value, the closest answer is 177 square inches.
