The area of circle Z is 64x ft?.
What is the value of ?

r= 4 ft
r= 8 ft
r= 16 ft
r= 32 ft

4 ft

Step-by-step explanation:

To calculate the area of a circle is πr^2

π means 3.142

r means?

Area of the circle is given as 64

So let solve the question

3.142×r^2=60

3.142r^2=60

Divide both sides by 3.142

r^2=19.096

Square root of both sides

r=4.37~4

Therefore the final answer for r is 4 ft

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.
