What do you need help with?
Step-by-step explanation:
Answer:
6 ft
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2
216 = 6s^2
Divide each side by 6
216/6 = 6s^2/6
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 =s
Each side is 6ft
P=2(l+w)
50=2(4+w)
50=8+2w
collect the like terms 50-8=2w
42=2w divide both sides by 2
w=21
Answer: 53 degrees
----------------------------------------------------------
Work Shown:
Add up the two arc measures and divide the result by 2
Angle CED = ((arc AB) + (arc CD))/2
Angle CED = ((90) + (16))/2
Angle CED = (106)/2
Angle CED = 53
