Question

Find the circumference of the circle when radius is 3.5 cm​

Answer 1

Answer:

Step-by-step explanation:

GIVEN RADIUS=3.5 cm

              ∴ circumference=2πr

                                            =2*22/7*3.5

                                              =22cm2

b. given radius=4.65cm

            ∴ area=πr*r

                        =22/7*4.65*4.65

                        67.95cm2

Answer 2

Given radius =3.5 cm

We know that, Circumference of the circle is C=2πr

=(2×22/7×3.5)

=(21×22/7)

=22 cm

Thus, the circumference of the circle is 22 cm.
