(9,13) would be another point that the line passes through.
If it’s rotating around something, it’s most likely a cylinder I believe
Answer:
200π
Step-by-step explanation:
Surface area of a cone = πr(r+l)
r is the radius
l is the slant height
Volume of the cone = 1/3πr²h
320π = 1/3πr²h
320 = 1/3r²(15)
320 = 5r²
r² = 320/5
r² = 64
r = 8
l² = 15² + 8²
l² = 225 + 64
l² = 289
l = 17
Get the surface area;
S = πr(r+l)
S = π8(8+17)
S = π*8*25
S = 200π
Hence the surface area of the cone is 200π
4004 + 50.50t = 300.75t
4004 = 300.75t - 50.50t
4004 = 250.25t
4004 / 250.25 = t
16 = t <=== they charge the same at 16 tons
300.75(16) = 4812 <== they cost the same

Answer:
It would cost 47.36
Step-by-step explanation:
First, you need to find out how many gallons are needed to fill the tank. To do this, simply multiply 25 by the fraction that is how much is already in there:
25 x
= 9.375
So that means that there is 9.375 gallons already in the tank. To find the amount needed to fill the tank:
25 - 9.375 = 15.625
So 15.625 gallons are needed, rounded up to 16 gallons because you cannot get a decimal value of gallons.
That means that 16 x the price = the amount to fill the tank:
16 x 2.96 = 47.36
So it would cost 47.36 to fill the tank!
