The formula for the volume of a right circular cone is V = . In solving for the volume of the first french fries cones V = = 75.398 . In solving for the height of the second french fries cones with a new radius of 4, the formula is rearranged to h = = = 1.5 in or inches. The height of the new cones will be 1.5 inches.
X=1/3 or x=-2 explanation: Find factors of 3 and 2 which subtract to make 5. We should realise that (3x2) - 1 = 5. Find the cross products and subtract to get 5. Add in the signs. One of the factors must be 0.
