1/2 + 1/3 = (3*1)+(2*1) / (2*3) = (3+2)/6 = 5/6
tinha 5/6 de litro
para 1 litro faltam 4/6 de litro
para 3 litros faltam 2 litros e 4/6 de litro ou, simplificando:
4/6 = 2/3, logo, faltam 2 litros e 2/3 de litro.
Radius is equal to 1/2 the diameter. The radius is 14 (28/2=14)
With your formula:
c=2*14
c=28
HOWEVER I believe you meant
c=2(pi)r
In which
c=2(pi)14
c=28(pi)
In this instance for pi we can use 3.14 since we will be rounding anyway, so
c=28*3.14
c=87.92
Rounded to be
c=88
Note:
If we didn’t round pi out to 3.14 we would have gotten 87.964594...
Answer:
it 14

Step-by-step explanation: The pictures show the work. So sorry about the delay -- my computer wasn't letting me type formulas, so I hand-wrote. If you have questions, let me know and I'd be happy to clarify, and if the pictures are sideways, use the rotate button at the top right.
