Answer:
Can you show a picture? Or like tell us the options?
A / [ pi r^2 ]<span> = θ / [ 2pi ] </span> [ multiply both sides by pi r^2 ]
A = [ θ / 2 ] r^2 = <span> (1/2)r^2 θ</span>
Find the ratio of the two similar sides that both dimensions are given.
The smaller triangle aide that is 4 units is the similar side of the larger triangle given as 8 units.
8 / 4 =2, this means the larger triangle is 2 times the size of the smaller triangle, which also means the smaller triangle is 1/2 the size of the larger triangle.
X on the smaller triangle is 1/2 11 units which equals 5.5 units.
Y is 2 times 3, which equals 6 units.
x = 5.5
y = 6
Anything from 650,000 to 749,999 because they would all round to the nearest hundred thousand to 700,000
