<u>Question</u><u>:</u></h2>
<u>find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm</u>
Required diagram :

<h3>Solution :</h3>
For a cylinder having a radius r and a height h ;
Volume Of Cylinder :
Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .
Converting ;
- 1 m³ = 1 × 10⁶ cm³ .
- > 1.54 × 10⁶ cm³ .
- > 1540000 cm ³.
- > π r² h = 1540000
- > 22/7 × 70 × 70 × h = 1540000
- > 22 × 10 × 70 h = 1540000
- > 15400 h = 1540000
- > h = 100 cm = 1 m.
<u>The</u><u> </u><u>height</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>cylinder</u><u> </u><u>is</u><u> </u><u>100cm</u><u>.</u><u>=</u><u>1m</u><u>.</u>
Answer:
C=5.1
Step-by-step explanation:
Using pythag (a²+b²=c²) we can determine c.
1²+5²=26
√26 = 5.099
c=5.1
Answer:
A
Step-by-step explanation:
Answer:
x = 2 for a, c, and f
Step-by-step explanation:
a)
6(2x - 1) = 4 + 7x
12x - 6 = 4 + 7x
5x = 10
x = 2
b)
10 - 3x = -2(x + 4)
10 - 3x = -2x - 8
18 = x
c)
-3(7 - 2x) = -1 - 4x
-21 + 6x = -1 - 4x
10x = 20
x = 2
d)
7x + 12 = 2(4x - 5)
7x + 12 = 8x - 10
22 = x
e)
-5(x + 1) = -4 - 7x
-5x - 5 = -4 - 7x
2x = 1
x = 1/2
f)
8x + 11 = 9(5 - x)
8x + 11 = 45 - 9x
17x = 45 - 11
17x = 34
x = 2
