what is area of the circle with a radius of 7 cm ?

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. For a circle with a radius of 7 cm:

\[ A = \pi (7)^2 = \pi \times 49 \approx 153.94 , \text{cm}^2 \]

Thus, the area of the circle is approximately \( 153.94 , \text{cm}^2 \).
