Its about 3.14 * 2.5^2 * 13.5 ( using formula V = pi r^2 h)

= 265 in^3 to nearest in^3.

You invested $500 in a savings account and after three years you had $650 in your bank. What was the interest rate? Use the equa

Answer:

An increase of 43.3% per year

Step-by-step explanation:

using the equation, plug in the respective variables. 650 =500R3, 3 times 500 is 1500. 650=1,500R. divide both sides by 1500 to get .4333, 3 repeating. .433 in percent form is 43.3%. (I just use 650 out of 500 or 650/500 which is 1.3 divided by 3 because 3 years to get the same amount)

In the world of right triangles why does a (squared) + b(squared) = c(squared)? thanks konrad streuli

BlackZzzverrR [31]

Answer:

Pythagoras Theorem

Step-by-step explanation:

Like you rightly stated, in a right angled triangle. The phenomenon you mentioned is what us called Pythagoras theorem which proved to us that the square of the length of the hypotenuse of a right angled triangle, is equal to the square of the length of the opposite side to the angle in question, and also to the square of the length of the side adjacent to the same angle in question.

Essentially,

a² + b² = c², where c is the hypotenuse and a & b is the length of the two other sides

Congruent distance is a term used for distance with equal measurements. EA and EB are congruent; FA and FB are also congruent

I've added as an attachment, the image of the complete question.

From the attached image of the circles, we have the following observations

Points A and B are at the centers of both circles
Point E is at the exact point of intersection of both circles
Point F is also at the exact point of intersection of both circles (opposite point E).

These observations mean that:

The distance from A to E and B to E are the equal (congruent)
The distance from A to F and B to F are the equal (congruent)

Hence,

<em>Distance EA and distance EB are congruent;</em>
<em>Distance FA and distance FB are congruent;</em>
