2. 3375 is said to be a perfect cube because 15 x 15 x 15 is equal to 3375.
Since 3375 is a whole number, it is a perfect cube.

Let the radius of a circle be 'r'. When it is doubled, it becomes '2r'.
Area of the circle = pie × r^ 2
Area of the circle with doubled radius
= pie × (2r)^ 2 = pie × 4r^ 2.
Hence, the area of the circle increases by 300% (option 3) when the radius is doubled.
Hope it helps you.
