A company is designing a circular logo for a product. The inner part of the logo is a circle with a radius of r inches. The logo has a boulder that is a concentric circle surrounding the inner circle. The area of the border is 14.5 square inches. The logo is shown.
Write an expression that represents the total area, in square inches, of the logo in terms of the radius, r, of the inner part of the logo. If the total area of the logo is 127 square inches, what is the approximate value of r? Show your work or explain your work.

no one knows lol

step-by-step explanation:

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

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
