Acentral angle of a circle measures 1.5 radians. if the radius of the circle is 3 cm, what is the area of the related sector?
a) 4.55 cm2
b) 6.75 cm2
c) 7.38 cm2
d) 8.24 cm2

Option B.

Step-by-step explanation:

we know that

The area of a circle is equal to

we have

substitute

Remember that

radians subtends the complete circle of area

so

by proportion

Find the area of the related sector for a central angle of radians

Let

x------> the area of the related sector

correct answer:

i^31 = -i

step-by-step explanation: i dont
