$\large\huge\green{\sf{Given:-}}$

area of circle= πr²radius of circle= 7ft

$\large\huge\green{\sf{ToFind:-}}$

area of circle= ??

$\large\huge\green{\sf{Solution:-}}$

$area \: of \: circle= πr² \\ = \frac{22}{7} \times (7) {}^{2} \\ = \frac{22}{7} \times 7 \times 7 \\ = 22 \times 7 = 154ft {}^{2}$

hence, area of circle is 154 ft²
