Volume problem.... Please help
vladimir1956 [14]

Answer:

c

Step-by-step explanation:

volume of cylinder = πr^2h

r = 6.5

h = 13+13+13 = 39

cylinder volume = 1647.75π cm^3

volume of one sphere = 4/3 π r^3

= 366.16π cm^3

space not occupied by tennis balls = 1647.75π-3(366.16π)=549.25π cm^3

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey's work? Kai
hodyreva [135]

Answer:

D. Kailey is not correct:  89.12 \times 10^5 is not written in scientific notation.

Step-by-step explanation:

We have been given that Kailey wrote 8,912,000 in scientific notation as 89.12 \times 10^5. We are asked to choose the statement that best describes Kailey's work.    

We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.  

Upon looking at 89.12 \times 10^5 , we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.

Therefore, option D is correct choice.
