In a circle of radius 10 cm, a sector has an area of 40 sq. cm. what is the degree measure of the arc of the sector? 72° 144° 180°

45 .85° degree measure of the arc of the sector.

Step-by-step explanation:

Given  : In a circle of radius 10 cm, a sector has an area of 40 sq. Cm.

To find  : What is the degree measure of the arc of the sector

Solution : We have given that

Radius   = 10 cm.

Area of sector = 40 sq. Cm.

Area of sector = .

Plug the values

40 =  .

40  =   .

40 =  .

On multiplying by 360 both sides

40 * 360 =  theta  * 314

14400 = Theta  *  314 .

On dividing both side by 314  

Theta = 45 .85°

Therefore,   45 .85° degree measure of the arc of the sector.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
