1. Which figure has a circumference of
31.4 centimeters?
Figure A Figure C
Figure B. Figure D

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 [tex]2\pi r[/tex]
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
[tex]2\pi *r[/tex]
= [tex]2*3.14*5[/tex] : [tex]\pi =22/7=3.14[/tex]
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
