Ben is 3 times as old as Daniel and is also 4 years older than Daniel. How old is Daniel?

1 answer:

B=3d and b=d+4

Since b=b we can say:

3d=d+4 subtract d from both sides

2d=4 divide both sides by 2

d=2

Daniel is 2 years old. (and Ben is 6 years old)

Answer:

V≈653

Step-by-step explanation:

In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)
