Right triangle ABC is shown below.

A similar right triangle would be created by a run of 8 and a rise of _?

20

Step-by-step explanation:

The ratio of rise to run is 5:2, so if the run is 8, the rise is correspondingly 4 times as much:

 rise : run = 5 : 2 = 20 : 8

A similar right triangle would be created by a run of 8 and a rise of 20.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
