Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
- The diameter of circular measure = 24 cm
We know that the perimeter of a circular shape is called the 'circumference', with the formula
- Circumference of a circle = C = 2πr
When the mirror is cut into half, the diameter gets half as well.
- Thus, the diameter of a half mirror = 24/2 = 12 cm
We know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm
300 ordered
80% of them are hi-def
so 80% of 300
is 0.8 x 300 = 240
240 of the ordered TV's are hi-def
or if you used the images
each inteval is 30 (because 10% of anything is its self minus a 0)
count up 8 intervals and count up by 30s
you get 240
