WebMultiply by 2 to get a new diameter of 8.14 meters. If you realize that if you change the radius by a certain factor, the Volume changes by the factor cubed. So, since you're changing the volume by 2.5, you basically change the radius by cbrt (2.5). 3 * cbrt (2.5) will give you the new radius then. 12 comments ( 16 votes) Upvote Downvote Flag WebApr 11, 2024 · Simply speaking, area is the size of a surface.In other words, it may be defined as the space occupied by a flat shape.
