Answer:

Given :-

  • The circumference of a circle is 106.76 cm.

To Find :-

  • What is the diameter of a circle.

Formula Used :-

\clubsuit Circumference of Circle Formula :

\longmapsto \sf\boxed{\bold{\pink{Circumference_{(Circle)} =\: 2{\pi}r}}}

\clubsuit Diameter Formula :

\longmapsto \sf\boxed{\bold{\pink{Diameter =\: 2r}}}

where,

  • r = Radius

Solution :-

First, we have to find the radius :

Given :

\bigstar Circumference of Circle = 106.76 cm

According to the question by using the formula we get,

\implies \sf 2 \times \dfrac{22}{7} \times r =\: 106.76

\implies \sf \dfrac{44}{7} \times r =\: \dfrac{10676}{100}

\implies \sf r =\: \dfrac{10676 \times 7}{100 \times 44}

\implies \sf r =\: \dfrac{74732}{4400}

\implies \sf\bold{\purple{r =\: 16.98\: cm}}

Hence, the radius of a circle is 16.98 cm.

Now, we have to find the diameter of a circle :

Given :

\bigstar Radius = 16.98 cm

According to the question by using the formula we get,

\longrightarrow \sf Diameter =\: 2 \times 16.98

\longrightarrow \sf Diameter =\: 2 \times \dfrac{1698}{100}

\longrightarrow \sf Diameter =\: \dfrac{3396}{100}

\longrightarrow \sf\bold{\red{Diameter =\: 33.96\: cm}}

\therefore The diameter of a circle is 33.96 cm .
