Question

circle of circumference is 39.6 find its area​

Answer 1

Answer:

circumferenc of ciricle=2pi r

Step-by-step explanation:

2pi r=39.6

22/7*r=39.6/2

22/7*r=19.8

r=19.8*7/22

r=6.3

area=pi r^2

= 22/7*6.3*6.3

=22*6.3*0.9

=124.74

Answer 2

Answer:

circumference is 39.6

2πr=39.6

r=63

then

area is

22×63×63/7

=198×63

12464

is the answer ok
