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

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
