Answer:
114.5 in³
Step-by-step explanation:
Volume of cone:
⅓ × 3.14 × 8² × 12
= 803.84 cm³
Volume of hemisphere:
⅔ × 3.14 × 8³
= 1071.786667 cm³
Total = 803.84 + 1071.786667
= 1875.626667 cm³
1 cm = 0.393701 inches
1 cm³ = 0.393701³ inches
Volume in in³:
1875.786667/0.393701³
= 114.4579471 in³

21 = 36 - 3y -36
-36+21 = -3y
- 15 = - 3y ÷ -3

I believe your answer is 12. Sorry if it's wrong!
Romeo spent $256,000, Baxter spent $243000 and Hirsch spent $81000 as determined by mathematical equation.
What is a mathematical equation?
- A fine statement called an equation is made up of two expressions joined together by the equal sign.
- Individualities and tentative equations are the two different types of equations.
- Only certain combinations of the variables' values make a tentative equation true.
- A good expression that uses the equals symbol is an equation.
Suppose Romero spent x.
x-13000 = Baxter
Hirsch's expenses equal (x - 13000)3
Making a mathematical equation out of it,
Romero, Baxter, and Hirsch equal 580000
x + x - 13000 + [(x - 13000)3] = 580000
2x + [(x - 13000)3] = 580000 + 13000
6x + x - 13000 = 593000 x 3
7x = 1779000 + 13000
x = 17920007
X = 256000
Thus,
According to a mathematical equation,
Hirsch spent $81,000,
Romeo spent $256,000,
Baxter spent $243,000.
