Answer:
1.9 inches
Step-by-step explanation:
We need to utilise one important formula in this question which is the volume of a cylinder formula. We need to work out the height of the cylinder given the following information that the radius is 8 inches and the volume is 384 cubic inches. We can set up an equation to find the value of the height so,
→ π × r² × h = 384
⇒ Substitute in 8 for 'r'
→ π × 8² × h = 384
⇒ Simplify
→ π × 64 × h = 384
⇒ Divide both sides by 64 to isolate π and h
→ π × h = 6
⇒ Divide both sides by π to isolate 'h' and find the value of the height
→ h = 1.9098593171
The height of a cylinder with a volume of 384 cubic inches and a radius of 8 inches is 1.9 inches
Answer:
b
Step-by-step explanation:
Answer:
the answer is #4 because the quadrant 1 starts at the top right and it goes counterclockwise
Step-by-step explanation:
To put something in scientific notation, you have to make it a number more or equal to 1, but less than 10 and multiply it by 10 or 10 to the power of any number. For example 3.8x10^5. If you multiplied that out, you would get 380,000. You would get this as you are moving the decimal to the left 5 times. Since it has a decimal point, you have to subtract one from the 5 powers of ten. This would leave you with 10^4, and those would be zeros due to the fact that you are moving up places. For another example, 2.6 x 10^-3. You would get 0.0026. This is because it is a negative power. If you move the decimal in 2.6 to the left, you would have to add 1 power. Since it is a negative power, you have to subtract it. It would then become 10^-2. You would then move the decimal two more places to the left. Therefore, your answer would be 0.0026. In conclusion, any number with one or more zeros behind or past the decimal point can be put in scientific notation. Just make sure the number is equal to or more than 1 and less than 10. Hopefully my examples helped, thank you for reading if you did. Good luck!
