Answer 1

Answer:141.39

Explanation:

To find the circumference of a circle of diameter 45cm using 3.142 as pi

C=πd

C=3.142×45cm

C=141.39cm

Answer 2

The circumference of the circle is 141.39 cm

Explanation:

Circumference of a circle C =
`\pi d` or 2
`\pi r`

If diameter d = 45 cm and
`\pi` = 3.142

Then C = 3.142*45

C = 141.39 cm
