Question

answer me this maths lesson circle

THIS IS YOUR TASK​

Answer 1

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!!!!!

Answer 2

Step-by-step explanation:

1. Diameter = 14cm

Circumference = 44cm

2. Radius = 14cm

Circumference = 88cm

3. Radius = 98cm
