Question

find the radius of circle whose area is 44cm​

Answer 1

The radius of circle is 3.74 cm

Step-by-step explanation:

GIVEN

Area = 44 cm

___________________________

To Find

Radius

___________________________

We know that,

Area Of Circle = π × r²

44 cm = 3.14 × r²

r² = 44 / 3.14

r² = 14.0127388535

r = √14.0127388535

r = 3.74335930061

Radius = 3.74335930061 cm

The radius of circle is 3.74 cm

Here we go , yo ^^'

$\red{\bigstar}$ Area of Circle

= π × r²

↠ 44 cm = 3.14 × r²

↠ r² = 44 / 3.14

↠ r² = 14.0127388535

↠ r = √14.0127388535

↠ r = 3.74335930061

↠ Radius = 3.74335930061 cm

$\therefore\underline{\boxed{\textsf{R = {\textbf{3.74}}}}} \qquad\qquad \bigg\lgroup\bold{Radius\ of \ the \ Circle} \bigg\rgroup$

Some Important Formulas related to the Circle :-
