Answer:
i) d = 14cm ; c = 44cm ( 2πr = 2 x 22/7 x 7= 44)
ii) r= 14 ; c = 88cm ( 2πr = 2 x 22/7 x 14= 88cm)
iii) c= 616cm
2πr = 616cm
2 x 22/7x r = 616
r = 616 x 7/2x22
r = 98cm
so d = 196cm
iv)c= 72.6 cm
2πr = 72.6cm
2 x 22/7x r = 72.6
r = 72.6 x 7/2x22
r = 11.55 cm
so d = 23.1 cm
Hope it helps!!!!!
Step-by-step explanation:
1. Diameter = 14cm
Circumference = 44cm
2. Radius = 14cm
Circumference = 88cm
3. Radius = 98cm
Diameter = 196cm
4. Radius = 11.55cm
Diameter = 23.1cm
