Answer:
2 (B)
Step-by-step explanation:
Area of circle formula= pi r^2
Radius of circle= diameter / 2
radius= 6
3.14x6^2 = about 113.04
Volume= base x height
So, height = volume/base
226/113.04 = 2
Answer= B. 2
<h3>Answer:</h3>
- no
- yes
- no
- yes
- yes
<h3>Explanation:</h3>
The distributive property is useful both for collecting terms and for eliminating parentheses.
1. 3x +1/4 -x +1 1/2 = x(3 -1) +(1/4 +1 2/4) = 2x +1 3/4 ≠ 4x +1 3/4 (no)
2. 2(3x+1) = 2·3x + 2·1 = 6x +2 = 2 +6x (yes)
3. 3(x+1) -(1+x) = (x+1)(3 -1) = 2(x+1) = 2x +2 ≠ 2x +3 (no)
4. 4(x+1)-x-4 = 4x +4 -x -4 = x(4-1) +(4-4) = 3x +0 = 3x (yes)
5. 5.5 +2.1x +3.8x -4.1 = x(2.1 +3.8) +(5.5 -4.1) = 5.9x +1.4 = 1.4 +5.9x (yes)
Answer:
m=-2
Step-by-step explanation:
m=y2-y1/x2-x1
m=-2-8/3-(-2)
m=-2-8/3+2
m=-10/5
m=-2
