Answer: The radius of the circle is 2.25 cm.

Step-by-step explanation:

Since we have given that

Circumference of circle = 14.13 cm

As we know the formula for "Circumference of circle":

$C=2\pi r\\\\14.13=2\times 3.14\times r\\\\14.13=6.28\times r\\\\r=\dfrac{14.13}{6.28}\\\\r=2.25\ cm$

Hence, the radius of the circle is 2.25 cm.

Step-by-step explanation:

4(a-3)=22

a-3=4-22

a-3=18

a=18+3

a=21

5(x-6)=65

x-6=65-5
