C: 38.47

D: 43.96

Answer 1

B: 21.99

recall that for a circle, circumference is given by:

circumference = 2π x radius

= π x diameter

we are given taht the diameter is 7 cm and π = 3.14

simply substitute these values into the formula for circumference:

circumference

= π x diameter

= 3.14 x 7

= 21.98

(the closest answer to this is B: 21.99)
