Question

6. If the circumference of a circle is 33 cm, find its diameter​

Answer 1

as we know that

circumference of circle pie×d

33=22/7×d

33×7/22=d

d=10.5 cm

so diameter of circle is 10.5 cm

Answer 2

Answer:

10.50

Step-by-step explanation:

circumference of a circle=2πr

so,  

     33=2*22/7*r .  (where . π=22/7)

       r=33*7/2*22

        r=5.25cm

then<

      diameter of circle=2*radius . (i.e . d=2r)

                  d=2*5.25

                   d=10.50cm
