Answer:
about 198 miles
Step-by-step explanation:
183.38
- 18.95
_______
164.45 divided by .87 is 198.0229885057
Use A' for A complement, etc. and n = intersection ∩.
n(A' n B')
=n(A u B)' by the de Morgan's law
=nU-n(nA+nB-n(AnB)) n(A u B) = nA + nB - n(AnB) and nX'=nU-nX
=400-(135+80-60)
=400-155
=245
10 x 8 = 80ft for the rectangle
To work out the area of the semi circle you do pi (3.14) x the radius squared, the radius is half the diameter.
3.14 x 4 squared
3.14 x16 = 50.24ftsqaured for the whole circle so you divide it by 2 which is 25.12ft squared.
And then finally you add 25.12 and 80 so your answer is 105.12 ft squared
