Question

Hey guys, could you please help me solve this math problem?

Find the area of each circle (Take pie = 3.14)

Answer 1

Answer:

Area of the circle is 452.16 $cm^2$

Step-by-step explanation:

The area of a circle with radius $r$ is $\pi \times r^2$.

The given circle has a radius of 12 cm. That is

$r=12\ cm$

The value of $\pi$ is approximated to 3.14.

Thus the area of the circle is calculated as,

$Area = \pi \times r^2=3.14\times 12^2 =3.14\times 144=452.16\ cm^2$

So the area of the circle is 452.16 $cm^2$

Answer 2

Here we have to find the area of the circle.

From the figure, we know that the radius of the circle is 12 cm

Formula to calculate the area of a circle :

Area = πr²

Putting the values in the above formula

Area = 3.14 × (12)²

       = 3.14 × 144

       = 452.16 cm²

hence, the area of the circle will be 452.16 cm²
