QUESTION➡



Taking π = 3.14, find the area and perimeter of the circle whose radius is 15 cm.




SOLUTION➡



Perimeter of a circle = π× d


= 3•14× 2× 15


= 94•2 cm




________________________________________


$Area \: \: \: of \: \: \: a \: \: \: circle =\pi \: \: r^{2}$



= 3.14× 15× 15


=706.5 cm ^ 2

Therefore,



Perimeter of the circle is 94.2 cm
