The globe arena in stockholm, sweden is the worlds largest hemispherical bulilding. the diameter of the arena is 110 meters. the globe arena is not a complete sphere, but if it were, what would iys volume be? round the volume to the nearest hundredth

The volume of a complete sphere is

                               V = (4/3 π) · (radius)³ .

The arena is not a complete sphere.
It's just half of a sphere.
So its volume is

                                 V = (2/3 π) · (radius)³

                                     = (2/3 π) · (55 m)³

                                     = (2/3 π) · (166,375 m³) .

                                     =      348,454.9852 m³

                                     =      348,454.99  m³ .  when rounded

The student council made more snow cones per hour than the parent volunteers.

Explanation:

To find the number of snow cones made per hour:

XXX

Divide the number of snow cones made

XXX

by the number of hours spent making snow cones.

Parent volunteers

XXX

Number of snow cones:  

120

XXX

Number of hours spent making snow cones:  

5

Number of snow cones per hour:  

120

÷

5

=

24

Student council

XXX

Number of snow cones:  

100

XXX

Number of hours spent making snow cones:  

4

Number of snow cones per hour:  

100

÷

4

=

25

Since the student council made  

25

snow cones per hour and the parent volunteers only made  

24

snow cones per hour:

the student council made more snow cones per hour.
