Find the circumference and the area of a circle with diameter 8.
Use the value for 3.14 pie , and do not round your answers.

Respuesta :

Answer:

Area = 50.24 units²

Circumference = 25.12 units

Step-by-step explanation:

Circumference [tex]= 2\pi r[/tex]

[tex]=\pi d[/tex]

[tex]=3.14\times 8[/tex]

[tex]=25.12[/tex]

Area [tex]= \pi r^2[/tex]

[tex]r = 8\div2[/tex]

[tex]=4[/tex]

Area [tex]= 3.14\times4^2[/tex]

[tex]=50.24[/tex]

∴ The circumference of the circle is 25.12 units, and the area of the circle is 50.24 units²

Hope this helps :)
