stealth61 [152]
 Total expense= sum of all expenses incurred 
                       = commission+legal fees+advertising+printing cost+accounting fees

Total amount of shares sold=$ 2000000 x $62.5
                                              =$ 125000000
commission= 4% of the total amount of shares sold                      = .04x12500000
                      =$ 5000000
total expenses= $5000000+$2255500+$450000+$324400+$386000
                        =$8415900
selling expense/share = $8415900/2000000
                                      =$4.21/shareThe total expense per share is $4.21.

Container A is cylinder with a radius of 10 units and a height of 10 units. A right cone has been carved from its base and has a
sergij07 [2.7K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

Height = 10 units

Radius = 10 units

Volume = π × 10² × 10

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Height = 10 units

Base = 10 units

Volume = 1/3 × π × 10² × 10

Since the cone has been carved from the cylinder, the statement that derives the formula to find the volume of container B is

π × 10² × 10 - 1/3 × π × 10² × 10
