Volume of the sphere = 900 cubic inch
Then
4/3 pi (r)^3 = 900
pi (r)^3  = (900 * 3)/4
             = 675
r^3 = 675/pi
      = 675/3.14
r^3 = 214.97
r = 6
Then
Surface area of the sphere = 4 pi (r)^2
                                            = 4 * 3.14 * (6)^2
                                            = 4 * 3.14 * 36
                                            = 452.16
                                            = 452
The surface area of the sphere given in the question is 452 square inches.

Mashutka [201]
<h3>Answer:  216 square feet</h3>

Work Shown:

Old area = 12*15 = 180 square feet

New area = 18*22 = 396 square feet

Difference = New - Old = 396 - 180 = 216

The patio's area increased by 216 square feet.

Metal A has a density of 12.7 g/cm3.
stira [4]

Using the given information, the density of metal B is 8.58 g/cm³

<h3>Calculating density </h3>

From the question, we are to determine the density of metal B

From the given information,

55 g of metal A is combined with metal B to create an alloy with mass 90 g

∴ Mass of metal B in the alloy = 90 g - 55 g = 35 g

Now, we will determine the volume of metal A in the alloy

Using the formula,

Density = Mass / Volume

∴ Volume = Mass / Density

Volume of metal A in the alloy = 55/12.7

Volume of metal A in the alloy = 4.33 cm³

Then, we will determine the volume of the alloy

Volume of the alloy = 90/10.7

Volume of the alloy = 8.41 cm³

∴ Volume of metal B in the alloy = 8.41 cm³- 4.33 cm³

Volume of metal B in the alloy = 4.08 cm³

Now, for the density of metal B

Density = mass / volume

Density of metal B = 35 / 4.08

Density of metal B = 8.58 g/cm³

Hence, the density of metal B is 8.58 g/cm³.

What is the Point slope equation
anastassius [24]

Answer:

y - y1 = m(x - x1)

Step-by-step explanation:

The point slope form equation is [ y - y1 = m(x - x1) ]

(x1, y1) is any given point on the line.

m is the slope.

To solve this you would need these things:

  • Slope (y2-y1/x2-x1)
  • Y-intercept (y = mx + b)

Best of Luck!
