First you have to know the equation which would be V=πr^2h so then you would plug each number in to get V=(3.14)*(4^2)*(13) which would get you V=(3.14*16)*(13) which equals V=50.24*13 which gives you V=653.12 so your answer is
V=653.12

marissa [1.9K]

Answer:

  • 34.13 years

Step-by-step explanation:

<u>Given formula:</u>

  • G(t)= 63000(1 + 0.0255/4)^4t

<u>Need to find the value of t when G(t) = 150000</u>

  • 150000 = 63000( 1+ 0.0255/4)^4t
  • ( 1+ 0.0255/4)^4t = 150000/63000
  • ( 1+ 0.0255/4)^4t = 2.3809
  • 4t* log( 1+ 0.0255/4) = log 2.3809
  • 4t *0.00275983965 = 0.37674115501
  • t = 0.37674115501/(4*0.00275983965)
  • t = 34.13 years rounded

Jessica and her sister have a combined age of 47. Jessica is 5 years older than her sister. How old is Jessica
maw [93]
Let the sister be x years old.
Then Jessica is x + 5 years old.
Their ages add to 47.

x + x + 5 = 47

2x + 5 = 47

2x = 42

x = 21

x + 5 = 26

Jessica is 26, and her sister is 21.

I really need help some one please

The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)

In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0. 

x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x -  8) in our factorization. 

You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
