Answer:
8 positive integers.
Step-by-step explanation:
One value of n would be 15 because 225 = 15^2.
Other values are 225 * n where 15n <= 1000 and n is a perfect square.
So n = 4 gives us 225* 4 = 900 which is a perfect square and 15*4 = 60.
n = 9 gives us 225 * 9 which is a perfect square and 15*9 = 135.
n = 16 gives us 225*16 and 15*16 = 240 , so OK.
n = 25 gives a perfect square and and 15*25 = 375 - so OK.
n = 36 gives a perfect square and 15*36 = 540 - so OK.
n = 49 gives a perfect square and 15*49 = 735 - so OK.
n = 64 gives a perfect square and 15*64 = 960 - so ok.
n = 81 gives a perfect square and 15 * 81 = 1215 so NOT ok.
The equation of a circle centered on origin is
x²+y²=r² where r is the radius, so r²=16 in our equation so the radius of the circle is 4
we now have a total of 8 45-45 right triangle with hypotenuse 4. a 45-45 right triangle with hypotenuse 4 has legs of length 2√2. our big square is then 4√2 on a side. square this to get the squares area, which is 32
Answer:
7 x 2, 14, the area, then use pie, 3.14 to get the circle

Answer:
80
Step-by-step explanation:
its because of addition
Answer:
p = 35
Step-by-step explanation:
180 - 125 = 55
180 - 90 = 90
55 + 90 = 145
180 - 145 = 35
p = 35
