At best by they have a 42" tv that sells for $1250 and is on sale for 15% and sales tax is 6.5%. what is the final cost?

The promotion is:
$1,250* (15/100)= $187.50

The price of television after promotion is:
$1,250- $187.50= $1,062.50

The sales tax is:
$1,062.50* (6.5/100)= $69.06

The final cost is:
$1,062.50+ $69.06= $1,131.56

The final cost of the television is $1,131.56~

Draw a diagram to illustrate the problem as shown below.

Calculate the volume of the empty cone.
V₁ = (1/3)π*(6 in)²*(10 in) = 120π in³

Calculate the volume of the sphere.
V₂ = (4/3)π*(1.5 in)³ = 4.5π in³

The volume that can be filled with flavored ice is 
V = V₁ - V₂ = 115.5π in³ = 362.85 in³

Th volume is 115.5π in³ or 362.9 in³ (nearest tenth)
