Answer:
150 cubic inches of water
Step-by-step explanation:
volume of a cylinder = πr²h
Volume of a cone 1/3(πr²h)
π = 22/7
r = radius
volume of a cone = 
x Volume of a cylinder
450 / 3 = 150 in³
Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters

Step-by-step explanation:
<u>Step 1: Define</u>
2x³ - x² - 4x + 9
x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 2(3)³ - 3² - 4(3) + 9
- Exponents: 2(27) - 9 - 12 + 9
- Multiply: 54 - 9 - 12 + 9
- Subtract: 45 - 12 + 9
- Subtract: 33 + 9

We know that 1 ft = 12 in.
The dimensions of the trunk of a car:
4 ft = 48 in wide, 3 ft = 36 in deep, 2 ft = 24 in tall.
V = 48 * 36 * 24 = 41,472 in³
41,472 in³ ≈ 4 * 10^4 in³
And the volume of the calculator:
V ( calc. ) = 3 * 4 * 12 = 144 in³
Answer:
Desi`s error is D ) The volume of the calculator is not about 60 in³.
