A circular mirror measures 24 cm in diameter.

Mathematics

Basile [38]2 years ago

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

ELEN [110]

Answer:

17 1/3 52/3

Step-by-step explanation:

3x+y=38

3x+2y=52

-y=14

y=-14

3x+-14=38

3x-14=38

3x=38+14

3x=52

3x/3=52/3

x=171\3

17 is a whole number then 1 divided by 3 . thus is x

Which simplified fraction is equal to 0.53?
Inga [223]

Answer:

53/100?

Step-by-step explanation:

I mean you can't really simplify it any more. There's no LCD, GCD. Can't divide it evenly.

To solve it I just looked at the number of places, (3 which mean 100.)

Then I looked at the numbers, (53.)

So you just turn that into a fraction...
