Answer 1

Answer:

plz mark me as BRAINIEST all the question is done

Step-by-step explanation:

(i) Given radius =10.5 cm

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

=(2×22/7×10.5)

=(21×22/7)

=66 cm

Thus, the circumference of the circle is 66 cm

(ii) 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

Answer 2

Answer:

Circumference of a circle=2×π×radius

= 2×3.14×3.5

=6.28×3.5

= 21.98 meter
