Question

the circumference of a circle is 31.4 cm find the radius and the area of the circle ?take π=3.14​

Answer 1

Answer:

circumference of circle = 31.4cm

Answer 2

Step-by-step explanation:

given,

circumference=2πr =31.4

π=3.14

to find,

radius=?

solve,

2πr=31.4

2×3.14×r=31.4

6.28×r=31.4

r=31.4/6.28

r=5

hence the radius will be 5cm.

and the area will be πr^2

=3.15×5×5

=78.5 ans.
