A large pizza at Angelo’s Pizzeria has a diameter of 14 inches. What is the area of the pizza? Use 3.14 for pi. Round to the nearest tenth.
The radius of the pizza is half of the diameter, so:
r = 14/2 = 7
To find the area, we use the formula:
A = πr^2
A = 3.14 x 7^2
A = 3.14 x 49
A = 153.86
Rounded to the nearest tenth, the area of the pizza is:
A ≈ 153.9 square inches.
To find the area of a circle, you can use the formula:
Area = π * radius^2
Given that the diameter of the pizza is 14 inches, the radius can be calculated by dividing the diameter by 2:
radius = diameter / 2
radius = 14 inches / 2
radius = 7 inches
Now, substitute the value of the radius into the formula:
Area = 3.14 * 7^2
Area = 3.14 * 49
Area ≈ 153.86 square inches
Rounding to the nearest tenth, the area of the pizza is approximately 153.9 square inches.
