## What is the ratio for the volume of two similar spheres?

Let a the side of the cube, so the smaller sphere has diameter a and the larger sphere has diameter a√3 (Pythagoras). Since the volume is proportional to the third power of the diameter, you have the ratio of the two sphere’s volumes as 33/2≃5.2 .

## How do you find similar volumes?

If two solids are similar, then the ratio of their volumes is equal to the cube of the ratio of their corresponding linear measures.

**What is the ratio for volumes of two similar spheres given that the ratio of the radii is 3 4?**

Two spheres have radii in a ratio of 3:4. What is the ratio of their volumes? If we cube 3 and 4, we will have the ratio of the volumes. Therefore, \begin{align*}3^3:4^3\end{align*} or 27:64 is the ratio of the volumes.

### What is the ratio for the volume of two similar spheres given that the ratio of their radii is 5 9?

Ratio of radii= 5:9. r1=5 , r2=9. Ratio of volume=>4/3πr1^3:4/3πr2^3.

### How do you find the ratio of volume to area ratio?

To calculate the S/V ratio, simply divide the surface area by the volume. We will examine the effect of size, shape, flattening an object, and elongating an object on surface-to- volume ratios.

**What does AA similarity mean?**

In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar . (Note that if two pairs of corresponding angles are congruent, then it can be shown that all three pairs of corresponding angles are congruent, by the Angle Sum Theorem.)

#### How do you do similarity?

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

#### What is a similarity ratio?

The RATIO OF SIMILARITY between any two similar figures is the ratio of any pair of corresponding sides. Simply stated, once it is determined that two figures are similar, all of their pairs of corresponding sides have the same ratio. An Equation that sets one ratio equal to another ratio is called a proportion.
