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)
My friend will answer in a sec just give him~ some time....!
Hopes this helps:
Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
Answer:
n=2
Step-by-step explanation:
(6n-7)+(8n+2)=23
14n-5=23
14n=28
n=2
