Where:
r: is the radius
For the 12-inch pizza we have:
And for the 6-inch pizza we have:
The ratio between A₆ and A₁₂ is:
Hence:
Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.

Hello,
There is a mistake: it is 816 cm² !!! (an area)
length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
Answer:
La anchura será de:
6 cm
Step-by-step explanation:
El formato original corresponde al 100%
Si se reduce un 60% quiere decir que:
100 - 60 = 40%
la reducción queda al 40%
entonces, por regla de tres:
15cm es al 100%
A cm es al 40%
A = 15*40/100
A = 6cm
Answer:
We have the equation
we leave the terms with x on the left side of the equation and the independent terms on the right side.
resolving for x we have that
Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when 
Then, for 
the equation hasn't solution
