WebArea of a circle, A = πr 2 square units. Circumference / Perimeter = 2πr units. Area of a circle can be calculated by using the formulas: Area = π × r 2, where 'r' is the radius. Area = (π/4) × d 2, where 'd' is the diameter. Area = C 2 /4π, where 'C' is the circumference (sometimes referred to as perimeter). WebPerimeter of a semicircle is the sum of the half of the circumference of circle and its diameter. As we know that, perimeter of circle is 2πr or πd. So, perimeter of a semicircle is 1/2 (πd) +d or πr +2r. Formula is Perimeter of a Semicircle = d (1/2 π + 1) or r (π + 1) Where, r is the radius and d is the diameter. 2.
