The diameter of a circular pizza pan is 16 inches. What is the area, to the nearest tenth, of the pan?
pi*r2 = area
r = diameter/2
201.1 in. squared
looks good to me.
To find the area of a circular pizza pan, you can use the formula for the area of a circle, which is pi times the radius squared.
In this case, you are given the diameter of the pan, which is 16 inches. The radius of a circle is half its diameter. So, you can calculate the radius by dividing the diameter by 2.
The radius would be 16 inches divided by 2, which is 8 inches.
Now, you can use the formula for the area of a circle, substituting the radius you just calculated.
Area = pi * (radius)^2
Area = pi * (8 inches)^2
To calculate the area to the nearest tenth, it's important to use an appropriate value for pi. For most calculations, the commonly used value for pi is 3.14159.
Area = 3.14159 * (8 inches)^2
By performing the calculation, you get:
Area ≈ 201.06192982 square inches
Rounding this value to the nearest tenth, you get the final approximate area of the pizza pan:
Area ≈ 201.1 square inches.
