Question
Senthia wants to build a round photo frame for her brother. If the radius of the photo frame is 8 cm, what is the photo frame’s circumference?(1 point)
cm

Answer 1

The circumference of a circle is calculated using the formula:

Circumference = 2 * π * radius

Given that the radius is 8 cm, we can plug this into the formula:

Circumference = 2 * π * 8
Circumference = 16π

Now, if we want a numerical value for this, we can use an approximation for π, such as 3.14:

Circumference ≈ 16 * 3.14
Circumference ≈ 50.24

Therefore, the circumference of the round photo frame is approximately 50.24 cm.
