8a The following three shapes are based only on squares, semi circles, and quarter circles. find the perimeter and the area of each shaded parts. Give your answers as completely simplified exact value in terms of pi (no approximations). I NEED THE ANSWER NOW, FIND AREA.

Step-by-step explanation:

The area is 32-64cm^2

if you look at it, ADC makes a quarter circle and so does ABC, so:

area of a circle:r^2 so

then since it’s a quarter circle, divide by 4 which gives you 16

and since there are 2 quarter circles 16(2) gives you 32

then you find the area of the square: 8(8) gives you 64 so to find shaded area subtract 64 from 32 and that’s the answer

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
