Answer: 72.9 in^3
Step-by-step explanation:
The softball is a sphere, and we know that the volume of a sphere is:
V = (4/3)*pi*r^3
where pi = 3.14 and r is the radius.
We also know that the radius is half the diameter, and the diameter is 5.2 in
r = 5.2in/2 = 2.6in
Then the volume is:
V = (4/3)*pi*(2.6in)^3 = 72.9 in^3
X = number of tickets sold in advance, and thus cheaper.
x + 206 = number of tickets sold at the door.
now, the ones sold at the door, are more expensive and is more than the early sold tickets, as you know is x + 206.
now, if the early ones cost each one 6 bucks, then the cost for all of them is 6*x, or 6x.
the ones sold at the door are 10 bucks each, and therefore their total cost is 10(x + 206).
now, we know sales in total for both was 6828, therefore,
and surely you'd know what that is.
how many were sold at the door? well, x + 206.
