Answer:
Step-by-step explanation:
Volume of cylinder formula:
<h3>Given</h3>
Find r by substituting given values:
- 64π = πr²*4
- 64π = 4r²π
- 16 = r²
- r = √16
- r = 4 m
Correct choice is A.
Answer:
x=100
Step-by-step explanation:
Because they are vertical angles, AEG=FEB
You can see that FED+DEB=FEB
Therefore, 80+20=FEB=100
Since FEB=100 and FEB=AEG
AEG=100
4x - 7 < 17
+ 7 + 7
4x < 24
4 4
x < 6
Solution Set: (6, ∞) and {x|x < 6}
Answer:
174 square centimetres
Step-by-step explanation:
The formula for finding the surface area of a rectangular prism is
SA = 2LW + 2LH + 2HW
Therefore surface area will be
= 2(11*5) + 2(11*2) +2(2*5)
= 2 * 55 + 2 * 22 + 2 * 10
= (110 + 44 + 20) square cm
Which gives you 174 square centimetres.
