Question

Math Perimeter, Area And Volume

Answer 1

Area= 706.86 cm²

Circumference= 94.35 cm

Diameter= 30 cm

Answer 2

`\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
