HELPZZZ

What is the best approximation for the circumference of the pizza?

Use 3.14 to approximate pi.

12.6 inches
25.1 inches
50.2 inches
100.5 inches

Answer 1

Diameter of pizza = 16 inches.

Radius of pizza = 16/2 = 8 inches.

Circumference of pizza = 2 pi r

Circumference of pizza = 2 × 3.14 × 8

Circumference of pizza = 50.24 inches.

So, approximate value of Circumference = 50.2 inches. ( 3rd option ).

Answer 2

Answer:

We know that 2r=16, thus r=8

Now to calculate circumference we use the formula 2 x pi x r = Circumference

Inserting the values we get 2 x pi x r = 2 x 3.14 x 8 = 50.24

Thus circumference = 50.24 inches
