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

  • Each slice of pizza(i.e radius)= 15cm


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

  • area of pizza= ??
  • circumference of pizza= ??
  • diameter of pizza= ??


\large\huge\green{\sf{FormulaRequired:-}}

  • area of circle= πr²
  • circumference of Circle=2πr
  • diameter of circle = 2 x radius


\large\huge\green{\sf{solution:-}}

Area of pizza= πr²

= 3.14 x (15)²

= 3.14x 225

= 706.5

= 706cm²(approx)

therefore, area of pizza = 706 cm²

  • circumference of circle= 2πr= 2x3.14x15= 94.2cm= 94cm (approx)

therefore, circumference of pizza= 94cm

for finding diameter ,

  • we know
  • diameter = 2X radius= (2x15)cm= 30cm

therefore, radius= 30cm
