Question

How many times 132 cm long wire can be wripped around a circle with diameter 7 cm

Answer 1

Answer:

6 times

Step-by-step explanation:

Taking pi as 22/7.

Now given length of wire is 132.
to find out the how it is wripped to construct a circle. with diameter 7.
we have to find area of the circle first then divide with 132.

diameter -7 , radius = 3.5.
circumference =2pir

2x22/7x3.5
2x22/2 = 22cm

Now we divide 132/22 = 6.

Therefore it can be wrapped around 6 times

Answer 2

Answer:

6 times

Step-by-step explanation:

First ;circumference of circle=$2 X \pi X r$

                                               =2 X 22/7 X 7.5 /2 {since;1/2 diameter =radius}

                                               =22$cm^{2}$

       

So; we have to find out how many times the wire can go around the circle.  

                                   

∴  132cm long wire can be wrapped around circle= $\frac{132}{22}$

                                                                                     =6 times
