Answer:
2.5 x
miles
Step-by-step explanation:
We are given that 1 light year ≈ 5.9 x
miles so:
- 4.3 x 10² light year · <u>5.9 x </u>
<u> miles </u> - 1 light year
Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:
≈25 x 
This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:
≈ 2.5 x
miles
The answer would be 8+14 because there are 4 sides not 2
Answer:

Step-by-step explanation:
Answer:
He confused the height and the diameter
Step-by-step explanation:
the formula should have looked like this
V= 3.14 (2.5)^2 (24)
the reason why it is 2.5 and not 5 is because 5 is the diameter so divide 5 by 2 and you get 2.5
V= 3.14 (6.25) (24)
V= 3.14 (150)
V= 471
