Question

Find the circumference for a circle pi = 3.142 diameter= 45cm​

Answer 1

Answer:

The circumference of the circle is 141.39 cm

Step-by-step 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

Answer 2

Answer:141.39

Step-by-step 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
