Question

First try was incorrect

Dora is baking cookies. The diameter of each cookie is 10
centimeters.
What is the circumference of each cookie (use 3.14 for pi and round to
the nearest tenth

Answer 1

31.5 centimeters

Explanation:

C = 2πr = 2 × 3.14 × 5 ≈ 31.4 centimeters

Rounding this value to the nearest tenth gives us:

C ≈ 31.4 ≈ 31.5 centimeters

Therefore, the circumference of each cookie is approximately

31.5 centimeters.

Answer 2

The circumference of each cookie is 31.4 cm.

Explanation:

The circumference of a circle can be found using the formula: C = πd, where C is the circumference and d is the diameter.

Substituting the given diameter of 10 cm into the formula, we get:

C = π(10)

C ≈ 31.4 cm

Rounding to the nearest tenth, the circumference of each cookie is 31.4 cm.
