Question

Please answer this!!!​

Answer 1

GIVEN :

Radius of circle = ${3x}^{2}$

TO FIND :

Circumference of circle

SOLUTION :

Circumference of circle = 2πr

= 2× π × ${3x}^{2}$

= 6π ${x}^{2}$

Answer 2

circumference of a circle

$\: \: \: \: \: \: = 2 \: \pi \: r \: cm$

= 2 × pi × 3x sq.

= 6x sq. × pi

$\: \: \: \: \: =6\pi x {}^{2} cm$

or 6 × 22/ 7

$\: \: \: \: \: = 18.8 {x}^{2} cm$

hope it helps you!!!
