Question

If circumference
of a cirle is 176 find its
diameter​

Answer 1

Answer:

Circumference of circle=2πr

176=22/7×2r

2r=176×7/22

2r=56

d=56units

Answer 2

Diameter​ is

A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.

  A Diameter has is made by its radius.

    and                 Diameter  = 2 × radius

       Also      Circumference = 2 × $\pi$  × r        ( where r is radius )

                                                                     and    = 22/7 or 3.14

 so,  if we find  radius then ,

                      r =   Circumference / ( 2 × $\pi$ )        (Given Circumference = 176)

                    r =   176 / ( 2 × $\pi$ )    

                   r =  176 / ( 2 × 22/7 )

                  r =  176 × 7 / ( 2 × 22)

                   r =  28 cm

                               Diameter  = 2 × radius

                               Diameter  = 2 × 28 cm

                               Diameter  = 56 cm
