Answer:
A
Step-by-step explanation:
The general formula for the volume of a right cone is as follows (also see attached):
V = (1/3) π r² h; where r = radius of base and h = height
In this case, it is given that r = x
also given :
height = 2 (base radius)
or
h = 2x.
Hence the formula becomes:
V = (1/3) π r² h
V = (1/3) π x² (2x)
V = (2/3) π x³ (answer A)
Answer:
7/2
Step-by-step explanation:
(3,2) (5,9): Slope -->
(9-2)/(5-3) = 7/2
Answer:
(-4,1)
Step-by-step explanation:
Multiply first equation by 2
4x+6y=-10
Then subtract with second equation you get:
y=1
So put the value in first equation you get :
2x+3=-5
x=-4
Answer:
112 in.³
Step-by-step explanation:
This box is a combination of two rectangular prisms:
bottom - 9 in. by 2 in. by 4 in.
top - 5 in. by 2 in. by 4 in.
total volume = 9 in. × 2 in. × 4 in. + 5 in. × 2 in. × 4 in.
total volume = 112 in.³
