The total cost for utilities last month is 353,571.43.
<h3>What is the total cost for utilities last month?</h3>
The total cost for utilities last month can be determined by multiplying the volume of the stadium by the cost per cubic foot.
The volume of the stadium can be determined by using the formula for the volume of a hemisphere.
Volume of a hemisphere = Volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
2/3 x 22/7 x 150³ = 7071,428.57
The total cost for utilities last month = 7071,428.57 x 0.05 = 353,571.43
