Area of the rectangle is 12 to the power of 2 (or you can just say squared) and that equals 144cm squared
the area of the circle is pi radius squared (in this case radius is 3) and it equals 9 pi squared
to get the shaded area that is last over with the circles removed you would have to do (144)-(9pi) (this part is unachievable without a calculator that has the pi symbol to fill in instead of just writing 3.14) and after you get the answer of that which is 115.725666118
and that amount you must do the same with so it would be
(115.725666118)-(9pi) and that equals ...............

Answer:
160 yards
Step-by-step explanation:
P=2l+2w
P=2(3w-8)+2(w)
432=2(3w-8)+2(w)
432=6w-16+2w
432=8w-16
432+16=8w
448=8w
w=448/8
w=56yards
l=3(56)-8
l=168-8=160yards
You would just have to divide 20 and 4.
20/4=5

Answer:
35000 - 2500m
Step-by-step explanation:
Height of the airplane before it starts descending = 35,000 feet
Rate of descend = 2500 feet per minute
This means for every 1 minute the height of airplane is decreasing by 2500 feet. So, for every "m" minutes the height of airplane will decrease by 2500m feet.
Let h(m) denotes the height of the airplane after m minutes. The equation for h(m) can be set up as:
Height of airplane at m'th minute = Original Height - Distance descended in m minutes
So,
h(m) = 35000 - 2500m
This expression describes the height of airplane after any number of minutes(m).
