what is area of the circle with a radius of 7 cm ? A 49cm b. 98cm c. 153.86 d. 308cm

1 answer

To find the area of a circle, you can use the formula:

\[ \text{Area} = \pi r^2 \]

where \( r \) is the radius of the circle.

In this case, the radius \( r \) is 7 cm.

Calculating the area:

\[ \text{Area} = \pi \times (7 , \text{cm})^2 \] \[ \text{Area} = \pi \times 49 , \text{cm}^2 \] \[ \text{Area} \approx 3.14 \times 49 , \text{cm}^2 \] \[ \text{Area} \approx 153.86 , \text{cm}^2 \]

So, the area of the circle is approximately 153.86 cm².

The correct answer is c. 153.86.
