Judy is baking a round cake for her niece's birthday and the recipe requires her to coat the bottom of the pan with flour. If the cake pan has an 8-inch diameter, what is the area that she will need to cover with flour on the bottom of the pan?

A = 50.24

Step-by-step explanation:

Diameter = 8

8/2 = 4

4 is the radius

A = πr2

A = 3.14 x 42

4 x 4 = 16

A = 3.14 x 16

A = 50.24

A = 50.24

Step-by-step explanation:

Diameter = 8

8/2 = 4

4 is the radius

A = πr2

A = 3.14 x 42

4 x 4 = 16

A = 3.14 x 16

A = 50.24

when you realize that you dont know just realize i just took a test and im so smart

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
