[tex]A = \pi \cdot 7^2 = 49\pi \approx 154 ~ ft^{2}[/tex]

[tex]\large\huge\green{\sf{Given:-}}[/tex]

  • area of circle= πr²
  • radius of circle= 7ft

[tex]\large\huge\green{\sf{ToFind:-}}[/tex]

  • area of circle= ??

[tex]\large\huge\green{\sf{Solution:-}}[/tex]

[tex]area \: of \: circle= πr² \\ = \frac{22}{7} \times (7) {}^{2} \\ = \frac{22}{7} \times 7 \times 7 \\ = 22 \times 7 = 154ft {}^{2} [/tex]

  • hence, area of circle is 154 ft²
