Question

Find the circumference of each circle. use 3.14 for

15 cm

Answer 1

The answer is:

C = 94.2 cm

Work/explanation:

The formula for the circumference is:

`\sf{C=2\pi r}`

where:

C = circumference

`\pi` = pi (3.14)

r = radius

Plug in the value of the radius:

`\sf{C=2*3.14*15}`

Simplify:

`\sf{C=94.2\:cm}`

Answer 2

To find the circumference of a circle, you can use the formula: circumference = 2 * π * radius.

Given that the radius of the circle is 15 cm, we can substitute this value into the formula to calculate the circumference.

Circumference = 2 * 3.14 * 15 cm

Circumference = 94.2 cm

Therefore, the circumference of a circle with a radius of 15 cm is 94.2 cm.
