The sum of the height and the radius of the base of cylinder is 34cm. If the total surface area of the cylinder is 2.992cm^3. Find radius

Step-by-step explanation:I don't say you have to mark my ans as brainliest but my friend if it has really helped you plz don't forget to thank me...

0.014 cm .

Step-by-step explanation:

I am assuming that it is a closed cylinder whose total surface area.

Area = 2πrh + 2πr^2

Let the radius be r and the height h,  then we have the equations:

r + h = 34

2πrh + 2πr^2  = 2.992

From the first equation  h = 34 - r, so substituting for h:

2πr( 34 - r) + 2πr^2 = 2.992

2πr^2 + 68πr - 2πr^2 = 2.992

68πr = 2.992

r = 2.992 / 68π

r = 0.014

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

faster, im not sure why but i know it is faster
