The answer would be 1,288.
23x56=1,288
Area=pi times r^2
circumference=2pi times r
we are given
area=144pi ft^2
therefor
area=pi r^2
144pi=pir^2
divide both sides by pi
144=r^2
squre root both sides
12=r
subsitute
circunference=2pi r
circunference=2 times pi times 12
circumference=24pi
answer is 24pi ft
if you were to aprox pi to 3.14 and multiply you would get 75.36 ft
A^(-b) = 1 / (a^b), so
5^(-3) = 1 / (5^3) = 1 / 125 = 0.008
Given that the two trianglea are right angles, this means that one of the angles is 90 degrees.
If one on the angles of triangle PQR is 30 degrees, then the third angle will be 60 degres.
Thus, the three angles of triangle PQR are: 90, 30, 60
If one on the angles of triangle MNO is 45 degrees, then the third angle will be 45 degres.
Thus, the three angles of triangle MNO are: 90, 45, 45
For two triangles to be similar, their angles has to equal.
Therefore, t<span>riangles PQR and MNO are not similar.</span>
