The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.
zlopas [31]

Answer:

x = 2.5

Step-by-step explanation:

Surface area of cylinder = 2πr(h + r)

Volume of cylinder = πr²h

Given that S.A = Volume of the cylinder, therefore, we have:

2πr(h + r) = πr²h

Radius (r) is given as 2.5 cm

height (h) = x cm

Input the values and solve for x

2πr(h + r) = πr²h

2πr(h + r) = πr(rh)

2(h + r) = rh (πr cancels πr)

2(x + 2.5) = 2.5*x

2x + 5 = 2.5x

Subtract 2x from both sides

2x + 5 - 2x = 2.5x - 2x

5 = 0.5x

Divide both sides by 0.5

\frac{5}{0.5} = \frac{0.5x}{0.5}

2.5 = x

x = 2.5

PLEASE HELP ASAP! What are the solutions to the system of equations?
musickatia [10]
Y=2x

so what you do is sub 2x for y in the top equation

x^2+(2x)^2=5
x^2+4x^2=5
5x^2=5
divide both sides by 5
x^2=1
sqrt both sides
x=1 or -1

sub back

y=2x

y=2(-1)
y=-2

y=2(1)
y=2


the solutions are (1,2) and (-1,-2)

A 450 square foot apartment in New York City cost 540,000. What is the price per square foot explain or show your reasoning
Anton [14]

The cost of per square foot is 1200.

Step-by-step explanation:

Given,

Total area = 450 Square foot

Total cost = 540000

Cost of per square foot = \frac{Total\ cost}{Total\ Area}

Cost\ per\ square\ foot=\frac{540000}{450}\\Cost\ per\ square\ foot= 1200

The cost of per square foot is 1200.
