a central Angle of a circle of radius 50cm intercept an arc of 10cm. express the central Angle in radian an degrees

 π/5 = 36°

Step-by-step explanation:

The formula for the arc length of a circle is:   s = r Ф   (Ф must be in radians)

Given: s = 10, r = 50

s = r Ф

10 = 50 Ф

(1/5)π = Ф     (We include π because it must be in radians)

Convert into degrees using the proportion π = 180°

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
