How much pizza sauce is needed to cover a 16" pizza? (Note: 16" is the diameter of the pizza.)
Responses
A 50.24 in^2
B 200.96 in^2
C 803.84 in^2
D 3215.36 in^2
C 803.84 in^2
To find the amount of pizza sauce needed to cover a 16" pizza, you first need to calculate the area of the pizza. Since the pizza is round, you use the formula for the area of a circle, which is A = πr^2, where r is the radius.
The radius of the 16" pizza is half of the diameter, so r = 8".
A = π(8)^2
A = π(64)
A = 64π or approximately 200.96 in^2
Therefore, approximately 200.96 in^2 of pizza sauce is needed to cover a 16" pizza.
200.96 in^2
is the correct answer. The radius is half the diameter, so r = 16/2 = 8. The amount of sauce needed to cover the pizza is the area. The area of a circle can be found using the formula A = π r^2
, where π ≈ 3.14 and r = 8.
A = (3.14)(8^2) = (3.14)(64) = 200.96 in^2
