There is a formula for the area of a sector given the radius and the angle measure.

n = angle measure
r = radius




Answer:
A.
Using the given formula, the calculated surface area would be in cubic units instead of square units.
Step-by-step explanation:
Answer:
Step-by-step explanation:
-6x²+15x+9=0
divide by -3
2x²-5x-3=0
2x²+x-6x-3=0
x(2x+1)-3(2x+1)=0
(2x+1)(x-3)=0
either x=-1/2
or x=3
Answer:
y=-2/19x
Step-by-step explanation:
slope=(y1-y2)/(x1-x2)=-2/19
y-intercept=0
y=-2/19x+0
