Answer

\pi r^2$.

The area of the circle is 153.86 cm².

Steps: The formula for the area of a circle is $A = \pi r^2$ . Given: Radius (r) = 7 cm $\pi$ = 3.14

Substitute the values into the formula: $A = 3.14 \times (7 cm)^2$
Calculate the square of the radius: $A = 3.14 \times (49 cm^2)$
Multiply by $\pi$ : $A = 153.86 cm^2$
