Drag and drop an answer to each box to correctly complete the derivation of a formula for the area of a sector of a circle
Suppose a sector of a circle with radius r has a central angle of 0. Since a sector is a fraction of a full circle, the ratio of
a sector's area A to the circle's area is equal to the ratio of the central angle to the measure of a
rotation of the circle. A full rotation of a circle is 27 radians. This proportion can be written as
-
Multiply both sides by Trp2 and simplify to get
1, where
is the measure of the
central angle of the sector and r is the radius of the circle.

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
