The volume of a cylinder is pi x r^2 (squared) x h.
H = Height
R = Radius.
Let's replace the letters with our numbers for this problem. (5, 3.14, 9)
Our new problem is 3.14 x 9^2(squared) x 5.
Now, what is 9 squared? We can get this by multiplying our number by itself. 9^2 (squared) = 9 x 9. 9 x 9 = 81. Now our problem is.
3.14 x 81 x 5. Now let's get our calculators out!
3.14 x 81 = 254.34. - 254.34 x 5 = 1271.7
In order to make our answer as a decimal to the hundredths place, we have to add a 0 to the right of our 2nd 7 (in the tenths place). 1271.70 can also be written as 1271.7.
Your answer is: 1271.70
As she gave out the reds in groups of 13 and the blues in sets of 20, our answer has to be divisible by both of these!
think of it like finding the lowest common denominator for a fraction!
in this case, the lowest number both go into is 260 (13X20)
Answer:
-2x+y = 4
y = 2x+4
Slope = 2 y-intercept = 4
Answer:
if you were roundind I say the ten stays the same
Answer:
about 130 hp
Step-by-step explanation:
The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:
(220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp
