Step one: correspond x values and y values together

it would be: 3, 12 and 4, 16

Step two: divide

12/3 = 4 and 16/4 = 4

both numbers = 4

**scale factor is 4**

The **surface area **of the large sphere is 128π cm²

<h3>Complete question</h3>

Two spheres have volumes of 8π cm3 and 64π cm3. If the surface area of the smaller sphere is 16π cm2, what is the surface area of the larger sphere?

<h3>How to determine the larger area?</h3>

The given parameters can be represented using the following **ratio**:

Small Area : Large Area = Small Volume : Large Volume

Substitute the given parameters

16π : Large Area = 8π : 64π

Express as **fraction**

Large/16π = 64π/8π

Multiply both sides by 16π

Large = 128π

Hence, the **surface area **of the large sphere is 128π cm²

well, a right-triangle has 90° total, so if one of the acute angles is taking up 74°, then the other is just 90° - 74°.

**Answer:**

3

**Step-by-step explanation:**

32 - 20 = 12

12/4 = 3

This assumes that by remainder they mean they twelve feet left over and not the twenty feet removed. This is likely what it means.

**Answer:**

y=1/3 x + 10/3
