Answer:
volume of a cone = 461.58cm³
Step-by-step explanation:
to find the volume of a cone
given the radius of the cone = 7cm
height of the cone = 9cm
recall that the volume of a cone = πr² h/3
volume of a cone = 3.14 x 7² x 9/3
volume of a cone = 3.14 x 49 x 3
volume of a cone = 3.14 x 147
volume of a cone = 461.58cm³
therefore the volume of a cone whose radius is 7cm , height is 9cm is evaluated to be equals to 461.58cm³
Idk but I think that the answer is (-6,-1)
Given,
The linear pair of the equation is,

Required
The solution of the linear equation.
Taking the equation first as,

Substituting the value of y in second equation then,

Substituting the value of x in first equation then,

Hence, the solution of the system is (1, -10).
First pair goes to f(x) = 20x
Next pair goes to f(x) = 10x + 20
Third pair goes to f(x) = 10x + 25
Last pair goes to f(x) = 20x + 10
Answer:
30% that he chooses red and 30% that he chooses blue.
Step-by-step explanation:
4+3+3=10
Probabilities that he chooses green = 4/10 = 40%
Red = 3/10 = 30%
Blue = 3/10 = 30%
