Answer:
Step-by-step explanation:
2πr = 12.56 cm
[tex]2*3.14*r=12.56\\\\r=\frac{12.56}{2*3.14}\\\\r=\frac{12.56*100}{2*3.14*100}\\\\r=\frac{1256}{2*314}=2[/tex]
r = 2 cm
r= 2cm
[tex]2\pi \times r = c \\ 2 \times \pi \times r = 12.56 \\ 6.28r = 12.56 \\ \frac{6.28r}{6.28} = \frac{12.56}{6.28} \\ r = 2cm[/tex]
