ans is 25
Step-by-step explanation:
12(10-5)-40+(4+1)
=12 of 5 - 40 + 5
= 60 - 40 +5
=60 +5 - 40
=65-40
=25
£9 - 90p = £8.10
2 Pencils = 48p
3 Pens = £1.11
3 Sharpeners = £2.31
All together = £3.90
£8.10 - £3.90 = £4.20
£4.20 / £1.40 = 3
Answer = 3 Notebooks
The volume of the entire rocket given the volumes of the cylindrical body and the cone nose is 117.23 in³.
<h3>What is the volume of the entire rocket?</h3>
The volume of the entire rocket is the sum of the volume of the cylinder and the volume of the cone.
Volume of the cylinder = πr²h
Where:
- π = 3.14
- r = radius 2
- h= height = 12 - 4 = 8 inches
3.14 x 2² x 8 = 100.48 in³
Volume of the cone = 1/3 πr²h
1/3 x 2² x 3.14 x 4 = 16.75 in³
Volume of the rocket = 100.48 + 16.75 = 117.23 in³

Answer:
Okay so you first need to figure out what your variables are in the equation given. It tells you pi is 3.14. on the top of the cylinder it shows that the radius (r) is 2. the height (h) is shown on the cylinder as 4. Now all you have to do is plug in the values for the variables into your calculator. You have (2) times (3.14) times the radius (2) and you square the radius. then you add (2) x (3.14) x (2) x (4). So if you put it in your calculator it would look like this: (2)(3.14)(2)^2+(2)(3.14)(2)(4)=75.36 Your answer is 75.36
