the sector of a circle has radius of 35 cm and central angle 135 o . find its perimeter ?
"perimeter of the sector = length of the arc + 2 ( radius ) = ( 135 / 360 * 2 * 22 / 7 * 35 ) + 2 ( 35 ) = 82.5 + 70 = 152.5 cm answer : c"
multiply(multiply(const_2, divide(multiply(subtract(35, const_3), const_2), add(const_4, const_3))), 35)
