Volume of a cone = pir^2h/3
so substitute what you know
1,102.14 = 3.14(r^2)(13/3)
divide by 3.14
351 = r^2(4.3333)
divde by 13/3
81 = r^2
r = 9 inches

Answer:
Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.
Step-by-step explanation:
Lăsați suma primului copil să fie x.
Lăsați suma al doilea copil să fie y.
Lăsați suma al treilea copil să fie z.
Trei dintre ei au 45 de lei în total.
Aceasta înseamnă că:
x + y + z = 45 ________(1)
Al doilea are de două ori valoarea primului:
y = 2x
Al treilea are cu 15 lei mai mult decât al doilea:
z = 15 + y
=> z = 15 + 2x
Puneți valoarea y și z în (1):
x + 2x + 15 + 2x = 45
5x = 45 - 15 = 30
x = 30 / 5 = 6 lei
=> y = 2 * 6 = 12 lei
=> z = 15 + 12 = 27 lei
Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.
Answer:
Four more than three times a number is greater than twenty-two.What is the number?
The number is greater than 6.
Step-by-step explanation:
Given:
Four more than three times a number is twenty-two.
Let the number be 'x'.
Three times of 'x' = '3x'
Four more means further four is added.
So,
The number is 
According to the question.
⇒ 
⇒ 
...Subtracting 4 on both sides
⇒ 
⇒ 
...Dividing 6 on both sides
Now if it says that it is greater than 22 then we will use 
sign.
So the number is greater than 6 'x' > 6.
