<u>Given:</u><u> </u>
- Circle with radius 5cm and 3 cm
<u>To </u><u>Find</u><u>:</u><u> </u>
- How much bigger is the area of a circle.
<u>Solution:</u>
Area of circle with Radius 5cm
Area of circle = πr²
Area of circle = 22/7 × 5 × 5
Area of circle = 22/7 × 25
Area of circle = <u>78.54 </u><u>cm</u><u>²</u>
Now,
Area of circle with Radius 3 cm
Area of circle = 22/7 × 3 × 3
Area of circle = 22/7 × 9
Area of circle = <u>28.27 cm²</u>
= 78.54 - 28.27
= 50.27cm
Hence,
- <u>Area of circle is 50.27</u><u>c</u><u>m</u><u> more than that area of circle with radius 3cm</u>
