does anyone know how what the angles would equal based on the diagram? any help will be appreciated:) <3

Asphere has a diameter of 10 in. what is the volume of the sphere?

Aschool puts on a play. the play costs $1,200 in expenses. the students charge $4.00 for tickets. there will be one performance of the play in an auditorium that seats 500 people. what is the domain of the function that shows the profit as a function of the number of tickets sold?  

Which type of graph would allow us to quickly see how many students between 100 and 200 students were treated?
