Answer 1

Answer:

C=2πr

Step-by-step explanation:

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

C

=

2

π

r

where:

C

=

circumference

r

=

radius

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

C = 2 π r  

c = 2 π

(

7

)

C

=

14

C

≈

43.98

∴

, the circumference is approximately  

43.98
