results for a dvd has a radius of 12cm. what is the diameter and circumference of the dvd? round to the nearest hundredth

Diameter: 24 Circumference: 75

Step-by-step explanation:

(equation for finding circumference: 2(3.14)r or 3.14d

2(3.14) x 12 = approximately 75 or 75.36

Diameter = r2

12(2) = 24

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
