Question

find the area of a circle of radius 30 cm(use π=3.14

Answer 1

Area of a circle = πr2

Radius ( r ) = 30cm

Area = 30×30×3.14
= 3×3×314
= 9×314
= 2826 cm 2

★Hence the required answer is 2826 cm2

Hope this helps!!
cheers!! (:

Answer 2

$\huge\bold\red{Question}$

Find the area of a circle of radius 30 cm (use $π = 3.14)$

$\huge\bold\green{Answer}$

$\bold{Radius,r = 30cm}$

$\bold{area\: of\: the\: circle = πr^2}$

⟹$\bold{3.14 \times {(30)}^{2}⟹3.14×(30)^2}$

⟹ $\bold{\frac{314}{100} \times 900}$

⟹$\bold{\frac{314}{1}\times 9}$

⟹ $\bold{2826\:cm^2}$
