Answer:

Area= 50.24 squared cm.

Circumference= 25.12 cm.

Step-by-step explanation:

To find the area of a circle- A= 3.14*(4 cm squared). ( The 4 cm is your radius. Half of the diameter.) After you square your radius you get 16cm squared. You then go onto multiply the 16 cm squared by 3.14 to get 50.24 cm squared.

To find the circumference of a circle- C= 2*(3.14)*(4cm). (Again the 4cm is your radius. Half of the diameter.) After you multiply the 2 and 3.14 you get 6.28. You then multiply the 6.28 by 4 cm to get 25.12 cm.

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

[tex]=\pi r^2\\\\= 3.14\times 4^2[/tex]

= 50.24 square centimeters

And, the circumference of the circle is

[tex]= 2\pi r\\\\= 2 \times 3.14 \times 4[/tex]

= 25.12 cm

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