Question

Find the area of a circle with a diameter of 6.

Answer 1

Answer:

A = 9pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the diameter

r = d/2 = 6/2 = 3

A = pi (3)^2

A = 9pi

Answer 2

Answer:

$28.26 \: \: {units}^{2}$

Step-by-step explanation:

$area \\ = \pi {r}^{2} \\ = 3.14 \times 3 \times 3 \\ = 28.26 \: \: {units}^{2}$
