![\large\huge\green{\sf{ToFind:-}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/f8wuljdqet3d6ueyqdtfeyni4wzirijdmc.png)
- area of pizza= ??
- circumference of pizza= ??
- diameter of pizza= ??
![\large\huge\green{\sf{FormulaRequired:-}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/3gubl6rg79w6u8nh6c0k0pjs76h8a9hf5w.png)
- area of circle= πr²
- circumference of Circle=2πr
- diameter of circle = 2 x radius
![\large\huge\green{\sf{solution:-}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/pizkvyppz4p5nx6ukdwqxolkifwkcbsva0.png)
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
