Answer 2

ÃÑSWËR :

(i) The circle with diameter 4.2cm.

So, its radius is = 4.2/2 = 2.1cm

Then, its circumference is

= 2×22/7×2.1

= 13.2 cm.

(ii) The circle with diameter 7cm.

so, its radius is = 7/2 = 3.5cm

Then, its circumference is

= 2 × 22/7 × 3.5

= 22 cm.

(iii) The circle with diameter 9.8cm.

so, its radius = 9.8/2 = 4.9cm.

Then, it's circumference is

= 2 × 22/7 × 4.9

= 17.6 cm.
