Question

7. Calculate the diameter of the circles having following circumference:
(a) 12 cm (b) 8.2 cm (C) 4.4 cm
(d) 22 cm
(e) 2.3 cm (f) 1.7 cm (g) 15.4 cm (h) 7.7 cm​

Answer 1

Step-by-step explanation:

a) 12cm

circumference of circle = 2πr

12= 2 x 22/7 x r

r = 12 x 7 / 2 x 22

r = 84/44

r= 1.91

d = 2r

d = 2 x 1.91

d = 3.82

do the other part of the question as same
