Answer:

Solution given:

B=12.56cm²

P=12.56cm

H=6cm

Surface area of cylinder=P*H+2B=100.48cm²

Volume=B*H=12.56*6=75.36cm³

Given:

A figure of cylindrical shape
Radius = 2cm
Height = 6 cm

To figure out :

Total surface area
Volume

Solution :

Note : Put the value of pi as 3.14

Volume = πr²h

3.14 × 2² × 6
3.14 × 4 × 6
3.14 × 24
75.36 cm³

Surface area = 2πrh + 2πr²

2πr ( r + h )
2 × 3.14 × 2 ( 2 + 6 )
12.56 × 8
100.48 cm²

X-5y=2 and 9x+8=15 solve by substitution

lozanna [386]

$x-5y=2$
Hence $x=2+5y$ (Equation I)
$9x+8=15$ (Equation II)
Substituting Equation I in Equation II
$9(2+5y)+8=15$
$18+45y+8=15$
$26+45y=15$
$45y=-11$
Hence $y= - \frac{11}{45}$

Substituting this in Equation in I to get X

$x-5(- \frac{11}{45} )=2$
$x+ \frac{11}{9}=2$
$x= 2- \frac{11}{9}$
$x= \frac{17}{9}$

Convert the following common fractions to decimals. Round to three decimal places if necessary. 5/6 = A)0.83 B)5.6 C)0.56 D)0.83

Umnica [9.8K]

Answer:

Step-by-step explanation:

If we divide 5 by 6 we'll come up with 8.333 repeating. It is necessary that we round to three decimal places since we have an endless amount of digits that can only be represented with 3 digits

1 . Solve 4x + 5 > 5x − 2 for x.

Kobotan [32]

I will do number 1 only. You can then use my solution steps to do the rest.

Solve 4x + 5 > 5x − 2 for x.

4x + 5 > 5x − 2

4x - 5x > - 2 - 5

-x > -7

Dividing both sides by a negative number reverses the inequality sign. In other words, the sign > becomes < in the reply.

-x/-1 < -7/-1

x < 7

Answer: x < 7

The answer here means that whatever the value of x is for question 1, it must be less than 7.

You finish.
