Find area and perimeter of shaded regions below

aleksandrvk [35]

Answer:

Step-by-step explanation:

ABCD is a square.

side = 24 cm

Area of square = side * side = 24 * 24 = 576 cm²

Semicircle:

d = 24 cm

r = 24/2 = 12 cm

Area of semi circle =πr²

= 3.14 * 12 * 12

= 452.16 cm²

Area of shaded region = area of square - area of semicircle + area of semicircle

= 576 - 452.16 + 452.16

= 576 cm²

Perimeter:

Circumference of semicircle = 2πr

= 2 * 3.14 * 12

= 75.36

Perimeter = 2* circumference of semicircle + 24 + 24

= 2 * 75.36 + 24 + 24

= 150.72 + 24 + 24

= 198.72 cm

The number of marbles of different colors stored in a hat is listed below:

ivann1987 [24]

Answer:

12.5%

Step-by-step explanation:

I warn you, I'm not positive I'm correct.

First I added 8+10+6 and got 24

I divided that by 3 and got 8

I divided 100 by 8 because if you cross multiply 1/8 and x/100 you would get 8x = 100

100 ÷ 8 = 12.5

So I got 12.5%

your phone says that 14.5% is equivalent to the decimal 14.5 explain why your friend is incorrect by comparing the fraction -14.

Lelechka [254]

A percent is a proportion of something that can come from a variety of different numbers depending on what you are measuring. 14.5% is not the same as 14.5 because the 14.5% isn’t necessarily 14.5 of a certain amount. For example, $14.50 of the $100 you have could be from your grandparents; making 14.5% of your money from your grandparents but a deposit of $145 into a bank account that already has $855 would mean that 14.5% of the money in that bank account was from that deposit but $145 does not equal $14.50. They just have the same proportion just different on different scales.

Hope this is what you were looking for.

I don't know how to solve this. Anything will help!

tigry1 [53]

Hello :) to solve this you would have to do invert sin (51/55) on your calculator. When you do that you will get 68.013 so I would round that and say that the angle is 68 degrees
