Question

Find the circumference and the area of a circle with diameter 8.

Answer 1

Answer:

Area = 50.24 units²

Circumference = 25.12 units

Step-by-step explanation:

Circumference $= 2\pi r$

$=\pi d$

$=3.14\times 8$

$=25.12$

Area $= \pi r^2$

$r = 8\div2$

$=4$

Area $= 3.14\times4^2$

$=50.24$

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

Hope this helps :)
