Question

What is the area of a circle with a radius of 12 cm.

Answer 1

Answer:

given that r=12cm

the area of a circle is πr^2

π×12^2

22/7×144

Answer 2

Answer:

The area of a circle is $452.39cm^2.$

Step-by-step explanation:

In context to the question asked,  

We have to find the area of a circle,

As per data given in the question,  

We have,

The radius of the circle = $12cm$

For calculating area,

The formula to be used for,

Area = $\pi r^2$

Substituting the values,

$=>\pi ( 12) ^2$

$=> \frac{22}{7}\times 12 \times 12$

$=> \frac{22}{7}\times 144$

$=> 452.39cm^2$

Hence, the area of the circle is $452.39cm^2.$
