Question

If the diameter of a circle is 28 cm its circumference

Answer 1

Answer:

circumference=2πr

π=22/7

r-=28/2=14cm

c=2x22/7x14

=2x22x2

thus circumference=88cm

Step-by-step explanation:

Answer 2

we will find the circumference using the formula Step-by-step explanation:

first find the radius =28/2=14cm

now put this radius in the formula 2pie r=2*22/7*14=88cm Ans
