Area And Perimeter Of Semi Circle Formula

Area And Perimeter Of Semi Circle Formula May 23 2022 0183 32 To determine the length of the arc we need the circumference of a semicircle Since the circumference is C R where C is the circumference and R is the radius we can define the formula for the perimeter of a semicircle which is

If we substitute the Area Formula for the circle we then arrive at the Area Formula for a semi circle Area 189 r 2 In case the diameter d is known and the radius is not known to us we can rewrite the radius as half of the diameter r frac d 2 In mathematical terms if a circle has a radius begin align r end align then the Area of the semi circle will be begin align frac 1 2 pi r 2 end align Perimeter will be begin align pi r 2r end align
