Answer:

1 hundred 12 tens and 2 ones = 222

Step-by-step explanation:

100+120+2 =222

Step-by-step explanation:

8 × 10000 + 0×1000 + 2× 100 + n + 6 x 1=0

80000 + 0 + 200 + n + 6 =0

80206n = 0

n = -80206

Each term is doubled
the equation is where an=nth term
a1=first term
n=which term

ok

so if the 9th term is x then the 10th term is 2x then 11th is 4x
so how much larger is the 11th term than the 9th term?
4x vs x
it's 4 times bigger or 400%

Answer:

Required A. radious of the cylinder is B. there is no change in radious due to change in height.

Step-by-step explanation:

Given volume of the cylinder is 728, that is we know for a cylinder with height h and radious r, volume V is,

A. To find radious of the cylinder :

which is the required radious.

B. To find change of radious due to change in height :

If the height h of the cylinder change to then radious,

From (1) we get,

Squaring both side we get,

Which shows that change of height dosen't effect on radious.
