Question

The radius of the circle is 14 cm. Find the radius of the circle whose area is double of the area of the circle ..
plz answer this it is urgent

Answer 1

Hi ,

1) given radius of the first circle ( r ) = 14 cm

    let radius of the second circle = R cm

    According to the given problem ,

area of the second circle = double the area of the first circle

                        πR² = 2 ×πr²

⇒                       R² = (2 × πr² )/ π

⇒                       R² = 2 × r²

⇒                       R = √2 ×r

∴                        R = √2 × 14

                          R = 14√2 cm

I hope this helps you .
