Answered by admin @


The area & circumference of the circle is 50.24 square centimeters and 25.12 cm.

Given that

  • The diameter is 8 cm so its radius is 4 cm.
  • And, the pie value should be 3.14

We know that

The area of the circle is

=\pi r^2\\\\= 3.14\times 4^2

= 50.24 square centimeters

And, the circumference of the circle is

= 2\pi r\\\\= 2 \times 3.14 \times 4

= 25.12 cm

Therefore we can conclude that The area & circumference of the circle is 50.24 square centimeters and 25.12 cm.
