Answer:
V=3926.99 liters
Step-by-step explanation:
cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?
Volume of a cylinder can be calculated using below formula
V=π r^2 h
Where r= radius
h= height
radius = 100 cm
h=250cm
But the cylinder is half filled, then the formula becomes
V=(π r^2 h) × 1/2
Then substitute the values we have
V=( π × 100^2 ×250) × 1/2
V=3926990 cm^3
But 1 litres = 1000cm3
Then V=(3926990 cm^3)/ 1000
V=3926.99 liters
Answer:
The slope is 3/8!
Explanation:
You put your equation in slope-intercept form, that is how you find the slope.
3x-8y=-20
-8y=-3x-20
y=3/8x-20
the fraction is now positive because the numerator and the denominator are both negative so they are changed into positive.

X3 + 4x2 -9x -36
[x3 + 4x2] -9 [ x+4]
take x2 common factor from first praket
x2[x+4] -9 [x+4]
= [x+4] *[x2 -9]
so the zeros of this equation are -4 , 3, -3
Answer:
(repeating, which is usually signified by a line over the 6, but I couldn't type that)
Step-by-step explanation:
________
15 | 4
__._____
15 | 4 0 since 15 is bigger than 4, add a 0 here.
make sure you also place a decimal point
above (above the place directly after 4) so your
answer isn't larger than it should be.
__.2____
15 | 4 0
3 0 15*2 = 30. that's as close to 40 as we're going to get.
__.2____
15 | 4 0
<u>-30 </u>
10 40 - 30 = 10.
__.2____
15 | 4 0
<u>-30 </u>
1 0 0 bring down an imaginary 0.
__.26___
15 | 4 0
<u>-30 </u>
1 0 0
<u> - 90 </u> 15*6 = 90. that's as close to 100 as we're going to get.
1 0
Notice that we keep getting 10 as a remainder again if we keep going. So 6 keeps repeating on top, which is why it's a repeating decimal. Once you realize it's the same number again and again the further you divide it, you can stop and write the line over the 6.
