Lets say pi is 3.14
The area of a circle is: pi*radius squared
The radius is half the diameter so it is 5 inches.
3.14*5 squared 2
3.14*25
78.5inches squared
<span>b-3/15=-1
We simplify the equation to the form, which is simple to understand
<span>b-3/15=-1
Simplifying:
<span>b-0.2=-1
We move all terms containing b to the left and all other terms to the right.
<span>+1b=-1 + 0.2
We simplify left and right side of the equation.
<span>+1b=-0.8
We divide both sides of the equation by 1 to get b.
<span>b=-0.8

Answer:
La familia de Gonzalo ha despilfarrado 15,768 litros de agua.
Step-by-step explanation:
Dado que Gonzalo observa que el grifo del lavabo gotea luego de un año, y el goteo se produce una velocidad de una gota por segundo y cada gota contiene 0.5ml de agua, para determinar cuántos litros de agua ha despilfarrado la familia de Gonzalo desde que ellos se dieron cuenta de la avería se debe realizar el siguiente cálculo:
1 año = 365 dias x 24 horas x 60 minutos x 60 segundos
0.5 x 60 x 60 x 24 x 365 = X
30 x 60 x 24 x 365 = X
1800 x 24 x 365 = X
43,200 x 365 = X
15,768,000 = X
15,768,000 / 1000 = X
15,768 = X
Por lo tanto, la familia de Gonzalo ha despilfarrado 15,768 litros de agua.
