Question

(1)
6. Find the diameter of a circle whose circumference is
(1) 66 cm
(m) 35.2 cm​

Answer 1

Answer: 21 m

Step-by-step explanation:

⟹πd=66

⟹

7

22

×d=66

⟹d=

22

66×7

=21 m

So the diameter is 21 cm

Answer 2

Answer:

1) 21 cm

2) 11.2

Step-by-step explanation:

1) Given: C. of circle= 66cm

πd= 66

d= 66/π

d= 66×7/22

hence, diameter= 3×7= 21 cm

2) similarly, diameter= 11.2 cm
