Question

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 ?

Answer 1

45X6²=1620 because the area of circle=r²
`\pi`

Answer 2

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.


`Area = \pi *r^2`


`r^2 = Radius`


`45*6^2= New \ Area`


`= 1620`
