Given :

⬤ Circumference of Circle is 132 unit .

To Find :

⬤ Radius of Circle .

⬤ Diameter of Circle .

Formula Used :

\bf{[\:Circumference\:of\: Circle=2\pi{r}}\:]

  • r = radius

Solution :

According to the Formula :-

2πr

132 = 2 × 22/7 × r

132 × 7 = 2 × 22 × r

924 = 44r

924/44 = r

21 = r

Therefore , The Radius of the Circle is 21 unit .

Now :

Diameter = R × 2

Diameter = 21 × 2

Diameter = 42

Therefore , The Diameter of Circle is 42 unit .

Answer:

Given that :

Circumference = 132 unit.

We have to Find :

Radius and Diameter of the circle.

Formula :

 \bf{ circumference \: of \: circle \:   = 2 \: π \: r}

According to the Formula :-

2πr

132 = 2 \times  \frac{22}{7}  \times r

r \:  =  \frac{132 \times 7}{2 \times 22}

r \:  = 21

Therefore , The Radius of the Circle is 21 unit .

Now :

diameter \:  = r \:  \times 2 \\ =  21 \times 2 \ \\  \: = 42

Therefore , The Diameter of Circle is 42 unit .
