Question

the area of a circle is 2826 sq.cm, find its radius(take π=3.14)​

Answer 1

★ Given :

• Area of Circle = 2826cm²
• π = 3.14

★ To Find :

• Radius of the Circle.

★ Solution :

$\sf : \implies\: Area \: of \: Circle = π \: r \: {}^{2}$

$\sf : \implies\: 2826 = 3.14 × r ^{2}$

$\sf : \implies\: 2826 ÷ 3.14 = r²$

$\sf : \implies\: 900 = r²$

$\sf : \implies\: 30 = r$

$\sf : \implies\:r = 30$

______________________________

Verification :-

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

$\sf : \implies\: 2826 = 3.14 × (30)²$

$\sf : \implies\: 2826= 3.14 × 30× 30$

$\sf : \implies\: 2826 = 3.14 × 900$

$\sf : \implies\: 2826 = 2826$

Hence Verified

Therefore, The Radius of Circle is 30 cm.
