Question

11. If the radius of circle is 7.5m find it’s area.​

Answer 1

Given:-

• Radius of circle = 7.5m

To Find:-

• It's Area

Formula used:-

• Area of Circle = πr²

Solution:-

$\implies\:Area \:of \:Circle \:= πr²$

$\implies\:Area \:of \:Circle \:= 3.14×7.5×7.5$

$\implies\:Area \:of \:Circle \:= 3.14×56.25$

$\implies\:Area \:of \:Circle \:= 176.625 m²$

Hence, The Area of Circle is 176.625 m².
