b. 75.40

Step-by-step explanation:

Circumference = 2pi * r

= 2pi * 12

= 24pi

= 75.39822369

Nearest hundredth: 75.40 cm

Laila Monroe · Answer 2

b. 75.40

Step-by-step explanation:

The circumference of a circle is the perimeter of the circle. To find the perimeter we would use the formula ⇒ 2 * π * r ⇔ or π * d ← where r is the radius and d is the diameter.

So lets substitute in the values

2 * π * r

Radius = 12

2 * π * 12 = 24 π = 75.3982236862

So the answer is b. 75.40
