Our aim is to calculate the Radius so that to use the formula related to the area of a segment of a circle, that is: Aire of segment = Ф.R²/2
Let o be the center of the circle, AB the chord of 8 in subtending the arc f120°
Let OH be the altitude of triangle AOB. We know that a chord perpendicular to a radius bisects the chord in the middle. Hence AH = HB = 4 in
The triangle HOB is a semi equilateral triangle, so OH (facing 30°)=1/2 R. Now Pythagoras: OB² = OH² + 4²==> R² = (R/2)² + 16
R² = R²/4 +16. Solve for R ==> R =8/√3
OB² = OH² +
The rest of the statement is (3x+1) = 3x²+22x+7.
The divisor is one factor, and the quotient is the second factor. The factors get multiplied to make the dividend.
The lest common multiple is 26. If you do multiples of each number
13:13,26
26: 26
Both of their lest common multiples would be 26
Well .5 of a million dollars is 500,000. so you are right the decimal of 500,000 is .5 million.
