The radius of a circle is 14 cm. Find its area in terms of piπ.

1 answer

The area \( A \) of a circle can be calculated using the formula:

\[ A = \pi r^2 \]

where \( r \) is the radius of the circle. Given that the radius \( r \) is 14 cm, we can substitute that value into the formula:

\[ A = \pi (14)^2 \]

Calculating \( 14^2 \):

\[ 14^2 = 196 \]

Now, substituting back into the area formula:

\[ A = \pi \cdot 196 \]

Therefore, the area of the circle in terms of \( \pi \) is:

\[ A = 196\pi \text{ cm}^2 \]
