Is the DIAMETER of a circle proportional to its circumference???
Elodia [21]

Answer:

Is the DIAMETER of a circle proportional to its circumference??

1. One of the unique qualities of a circle is that its diameter and circumference have a proportional relationship.

2. This means that no matter what size the circle is, the proportional relationship, or ratio, between its circumference and diameter is always the same.

Is the RADIUS of a circle proportional to its area??

1. Yes, the circumference of a circle is proportional to its radius.

2. Double the radius and you double the circumference.

The mass of a proton is approximately 1.67 x 10−24, and the mass of an electron is approximately 9.11 x 10−28. Find the approxim
nataly862011 [7]

Answer:

≈ 1833

Step-by-step explanation:

To find ratio of proton mass to electron mass, we have to divide.

The numbers are given in <em>scientific notation</em>.

Let a number be  a*10^b and another be  c*10^d, when we divide, we will follow the rule shown below:

\frac{a*10^b}{c*10^d}=(\frac{a}{c}*10^{b-d})

Now, we use the information given to find the ratio:

\frac{1.67*10^{-24}}{9.11*10^{-28}}\\=(\frac{1.67}{9.11}*10^{-24--28})\\=0.1833*10^4

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

0.1833*10^4=1833

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
