Question

If the radius of a circle is 7cm ,what will be its circumference?​

Answer 1

Step-by-step explanation:

According to the question

given data : r = 7cm

so circumference of circle is given by 2πr

by putting radius we get

circumference = 2×π×7

=2×3.14×7

=6.28×7

=43.96cm

Answer 2

Step-by-step explanation:

The circumference of a circle can be calculated with the formula:

C=2πr

where:

C=circumference

r=radius

To find the circumference, substitute your known values into the equation:

C=2πr

C=2π(7)

C=14π

C≈43.98 cm
