Answer:

Step-by-step explanation:

A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).

In a graph, a proportional graph is a graph that goes straight through the origin.

Answer:

Step-by-step explanation:

The ratio of its areas is equal to

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem the scale factor is equal to the ratio 10:3

Let

z-------> the scale factor

z2=(10/3)2=100/9

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra

luda_lava [24]

The surface area of a sphere is $A = 4 \pi r^{2}$ and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.

For example, let us assign values.
Let A=90

A= 90*9 = 810

$90 = 4 \pi r^{2} 

$ and $810 = 4 \pi r ^{2}$

the first r is 2.68 and the second r is 8.03

then, $\frac{8.03}{2.68} = 2.99626$ or rounded off to 3.
