Question

Find the area of a circle diameter equals to 30 cm​

Answer 1

Answer:

The area of the circle is

$225\pi$

Step-by-step explanation:

The diameter equals 30 cm, so the radio equals 15 cm.

The formula of the circle area is

$\pi \times {r}^{2}$

Then,

$\pi \times {15}^{2} = 225\pi$

Answer 2

Answer:

225Pi (in terms of Pi)

Or

706.5cm

Step-by-step explanation:

Area = Pi * radius^2

Radius is half of the diameter, so it is 15.

Area = Pi*15^2

Which is:

225Pi

Or

706.5
