What happen to area of circle, if its radius is doubled? write it's moral value also |
|
Answer» when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will ALWAYS go up by the SQUARE of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or DIAMETER) -- you just multiply it by pi. |
