Question

if the circumference of a circle is 33cm,then find its diameter??

Answer 1

Answer: circumference of a circle=2r×π

We know that diameter =2r

33 = d×π

33÷π=d

33×7/22=d

21/2=d

d=10.5cm

Most simplified way

Answer 2

Answer:

so the diameter is 10.52

Step-by-step explanation:

Circumference of circle = 2$\pi$r

                                 33  = 2*22/7*r

                      33*7/2*22 = r

                                   r    = 21/4

                                   r     = 5.25

so diameter will be 2r

=>     2(5.25)

=>    D= 10.50
