2⇒ Area =3.14×(25)

2 =78.5cm

2

Step-by-step explanation:

Circumference of the circle =31.4cm

∴2πr=31.4

⇒2×3.14×r=31.4

⇒r=5cm

Now again as we know that the area of the circle is given as-

Area =πr

2

⇒ Area =3.14×(25)

2

=78.5cm

2

Hence the radius and area of the circle is 5cm amd 78.5cm
