A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. What is the length of the radius of the circle? Round your answer to the nearest whole cm. Use 3.14 for Pi.

15 cm.

Step-by-step explanation:

It is given that,

Central angle

Arc length = 33 cm

Formula for arc length :

where, s is arc length, r is radius and is central angle in radian.

Substitute s=33 and in the above formula.

Multiply both sides by 10.

Divide both sides by .

Put

Therefore, the radius of the circle is 15 cm.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
