The radius of a circular plate is 3.5cm calculate its circumference π=3.14 correct answer to 1 decimal place value

Answer 1

To calculate the circumference of a circular plate, you can use the formula:

Circumference = 2 * π * radius

Given that the radius of the circular plate is 3.5 cm and π is 3.14, we can substitute these values into the formula:

Circumference = 2 * 3.14 * 3.5

Circumference = 21.98

Therefore, the circumference of the circular plate is approximately 21.98 cm when rounded to one decimal place.
