Answer 2

⭐⭐ Hey mate ⭐⭐

Here is the answer :-

a. 28 cm

Given ,

radius = 28 cm

As we know ,

circumference = 2πr

Thus ,

=> 2 × 22/7 × 28

=> 44 × 4

=> 176 cm

$\boxed {circumference\;=\;176cm}$

b. 42 cm

Circumference = 2πr

=> 2 × 22/7 × 42

=> 44 × 6

=> 264 cm

$\boxed {circumference\;=\;264cm}$
