Question

find the area of a.sector of a circle with radius 10.5 cm If angle of the sector is 60°​

Answer 1

Answer:

Step-by-step explanation:

From the data given in the question we know that

radium is equal to the= r = 10.5 cm and the angle is equal to = x =  60 degree .

so the formula for finding perimeter of angle 60 degree  = length of arc +2*radius

so            the perimeter will be    =(x/360°) 2πr + 2r

By putting the values we will got = (60°/360°)( 2 *3.14 * 10.5) + 2* 10.5

 So upon solving  the perimeter of sector will be = 32 cm

Answer 2

ANSWER

32cm

Step-by-step explanation:

radium is equal to the= r = 10.5 cm and the angle is equal to = x = 60 degree . So upon solving the perimeter of sector will be = 32 cm.
