What is the area of the segment if the angle theta 80 degre

What is the area of the segment if the angle theta = 80 degree?

Solution

Her the radius is 8.5 - 1 = 7.5

Central angle is 80 degrees

Area od segment = pi r²( angle / 360)

= 3.14 * 7.5 * 7.5 * ( 80 / 360)

=176.625( 80/360)

=14130/360

=39.25

Therefore, area of segment is 39.25 cm² .
