Step-by-step explanation:
You want to multiply the numerators and the denominators
Try this solution:
rule: the volume of any cylinder can be calculated with formula: V=πr²h, where r - the radius of the base, h - height of the cylinder.
Using the formula written above:
5. V=π*25*6=150*3.1415≈471.2389≈471.2 cm³;
6. V=π*64*4=256*3.1415≈804.2477≈804.3 cm³
Answer:

Answer:
x =20
Step-by-step explanation:
We can use similar triangles and proportions to solve. Take the smaller triangle side on top and the larger triangle side on the bottom.
11 10
---------- = --------------
11+121 10 +5x+10
Combine like terms
11 10
---------- = --------------
132 5x+20
Using cross products
11*(5x+20) = 10*132
55x+220 = 1320
Subtract 220 from each side
55x+220-220 = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
