Find the volume of a right circular cone that has a height of 19.7 ft and a base with a diameter 9 ft. Round your answer to the nearest tenth of a cubic foot.

V = 417.8 ft³

Explanation:

The volume (V) of a right circular cone can be calculated as follows:

Where:

r: is the radius of the circular cone

h: is the height of the circular cone = 19.7 ft

The radius of the circular cone can be found using the diameter (d) of the cone's base:

Now, the volume is:

Therefore, the volume of a right circular cone is 417.8 ft³.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
