Answer:
The volume of the cone = 28 inch³
Step-by-step explanation:
First let's consider the formula for the volume of the shapes
For cylinder
Volume= πr²h
For cone
Volume= 1/3 πr²h
So we'd notice that no much difference except that the volume if a cylinder is divided by two to get that off a cone.
So if the volume of the cylinder is
84π inch
The volume of the cone is 84/3 = 28
The volume of the cone = 28 inch³
Answer:
C
Step-by-step explanation:
∆=b^2-4a*c=1-4*3*(-10)=121>0 có 2x
x1=-b+sprt∆/2a=1+sprt121/2*3=2
x2=-b-sprt∆/2a=1-sprt121/2*3=-5/3
