Answer:

y = 7

Step-by-step explanation:

The diagonals of a rectangle are congruent and bisect each other, then

AC = BD , that is

AE + EC = BD [ AE = EC = 6y ]

6y + 6y = 84

12y = 84 ( divide both sides by 12 )

y = 7

​how many meters is the circumference of a circle with a radius of 20 cm?
Harman [31]
First find the circumference of the circle.
Circumference: 2 \pi r

Plug in 20 for the radius (r).
2 \pi20 = 125.66 

The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.

Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26

The circle's circumference is 1.26 meters.
