If the radius of a circle with an area of 45 inches squared is multiplied by 6, what is the area of the new circle ?

Respuesta :

45X6²=1620  because the area of circle=r²[tex] \pi [/tex]   
A circle is drawn with all it's points equidistant from a fixed point. The fixed point is called the center of the circle and the distance from the center point to the outside is called the radius. 

[tex]Area = \pi *r^2[/tex] 

[tex]r^2 = Radius [/tex] 

[tex]45*6^2= New \ Area[/tex] 

[tex]= 1620[/tex]
