Answer:

Okay so you first need to figure out what your variables are in the equation given. It tells you pi is 3.14. on the top of the cylinder it shows that the radius (r) is 2. the height (h) is shown on the cylinder as 4. Now all you have to do is plug in the values for the variables into your calculator. You have (2) times (3.14) times the radius (2) and you square the radius. then you add (2) x (3.14) x (2) x (4). So if you put it in your calculator it would look like this: (2)(3.14)(2)^2+(2)(3.14)(2)(4)=75.36 Your answer is 75.36

Need Help with 44.. picture above
Daniel [21]

Answer:

Ok:

Step-by-step explanation:

I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

miss Akunina [59]
20100 = 16000 * (1.02)^ t

20100/16000 = 1.02^t

1.25625 = 1.02^t

log 1.25625 = t * log 1.02

t = log 1.25625 / log 1.02
= 11.5
