word problem

You and 3 friends order a 24 in pizza (the diameter is 24 inches)
what is the area of the pizza?
Round to the nearest tenth.
If you and 3 friends spit the pizza evenly, how much do you get to eat?

What is total area?
and what is your area?
for total area i got 452.16 in squared
my area is : 150.72 in squared

is this right?

Your area is correct -- except you didn't round it to the nearest tenth.

Your part is not correct. Remember that four of you split the pizza.

area is : 452.2

split by 4 people 113.1 in
your area : 113. 1

is that right?

Yes. :-) Now you're right.

To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. In this case, since the diameter of the pizza is given as 24 inches, we can find the radius by dividing the diameter by 2. Therefore, the radius is 24 ÷ 2 = 12 inches.

To find the total area of the pizza, substitute the value of the radius (12 inches) into the formula:

A = π(12)^2
= π(144)
≈ 452.16 in² (rounded to the nearest tenth)

So, your calculation for the total area of the pizza is correct.

Now, to find out how much each person gets to eat when evenly splitting the pizza, divide the total area by 4 (you and your three friends). Therefore:

Your area = Total area ÷ Number of people
= 452.16 in² ÷ 4
≈ 113.04 in² (rounded to the nearest tenth)

So, it seems there was a calculation error in determining your area. Your area should be approximately 113.04 square inches.

To summarize:
Total area of the pizza ≈ 452.16 in²
Your area ≈ 113.04 in² (rounded to the nearest tenth)
