Circumference of circle=2πr=πd
15.7=πd
15.7=3.14d
15.7÷3.14=d
5=d
The diameter of the circle is 5cm.
15.7=πd
15.7=3.14d
15.7÷3.14=d
5=d
The diameter of the circle is 5cm.

given ,
circumference of the circle = 15.7 cm
therefore ,
circumference = 2πr
15.7 = 2 * 22/7 * r
15.7 = 44/7 * r
15.7 * 7/44 = r
2.49 = r
therefore radius of the circle = 2.49 cm and
diameter of the circle = 2.49 * 2 = 4.98 cm
therefore the answer is 4.98 cm .
i hope it helps..........................^_^
