Question

Find the circumference of the pizza use 3.14 the pizza is 7 inches

Answer 1

21.99

Formula: C=2 pi r
First, turn the diameter to a radius by dividing 7 inches, the diameter, by 2. This turns out to be 3.5 inches.
Then, multiply 3.5 by pi(3.14), which would give you 10.99 inches.
Last, do the last step of the formula, which is multiplying 10.99 inches by 2.

Answer 2

45 inches

Explanation:

C = (pi)(diameter).

Assuming that the radius of the pizza in this case is 7 inches, the diameter is twice that, or 14 inches.

Thus, the circumference of the pizza is C = (3.14)(14 inches) = 45 inches

approximately.
