The scale factor for area is the square of the scale factor for linear dimensions. When we talk about a scale factor without qualification, we mean the scale factor for linear dimensions.
-- They are unequal
-- The area of the circle is (pi) (radius²) = 19.63 inches² .
-- The area of the square is (side length)² = 25 inches² .
-- The area of the square is 27.3% greater than the area of the circle.
By definition, the area of a circle is given by:
Where,
r: radius of the circle.
Substituting the values in the given expression, we have:
Rounding to the nearest tenth we have:
