Trig: a sector of a circle has area 25 cm2 and centralangle
0.5 radians. find its radius and arc length.

 Radius = 10 cm and Arc length = 5 cm

Step-by-step explanation:

The area of a sector with radius r and central angle (In radian) is given by :-

Given : A sector of a circle has area and central angle  0.5 radians.

Let r be the radius , then we have

Thus, radius = 10 cm

The length of arc is given by :-

Hence, the length of the arc = 5 cm

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
