Question

1. Which figure has a circumference of

Answer 1

Answer:

Figure B

Step-by-step explanation:

Circumference of a circle is simply the length of the boundary of the circle which can be measured by the formula of $2\pi r$

In the figure B the given radius in the figure is 5

Putting 5 in the formula to find the circumference of the circle gives

                   $2\pi *r$

                = $2*3.14*5$                                                :                  $\pi =22/7=3.14$  

           Circumference of the circle in fig B = 31.4 cm

So, Circle in the figure B will have the circumference of 31.4 cm. Also the Circumference of the fig A, C and D are different and are not equal to 31.4 cm
