Answer 2

__________________❣️

We know that circumference of circle is

2πr

So radius =60/2

r=30 cm

AtQ

=2×22/7×60

=44/7×30

=1340/7

=188.5 71428571 cm

So circumference is 188.571428571 cm...

.....

We know that area of circle is

πr^2

AtQ

=22/7×30×30

= 19800/7

= 2828. 57142857 cm^2

So area is 2828.57142857 cm^2
