In geometry, Heron's (or Hero's) formula, named after Heron of Alexandria, states that the area A of a triangle whose sides have lengths a, b, and c is square root of semi perimeter multiply by semi perimeter minus a multiply by semi perimeter minus b multiply by semi perimeter minus c.
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)

Calculate the area of a rectangle and of the semicircle separately, then add.
Its perimeter is half of its circumference plus its diameter
Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.
The semi-circle is 0.5 X pi X diameter + diameter The semi-circle is 0.5 X pi X diameter + diameter
In geometry, Heron's (or Hero's) formula, named after Heron of Alexandria, states that the area A of a triangle whose sides have lengths a, b, and c is square root of semi perimeter multiply by semi perimeter minus a multiply by semi perimeter minus b multiply by semi perimeter minus c.
Area = pi*a*b where a and b are the semi-major and semi-minor axes.
Area = pi*a*b where a and b are the semi-major and semi-minor axes.
Oh honey, to find the area of a triangle in C, you need the base and height, then use the formula 0.5 * base * height. For the perimeter, you add up all three sides. Just make sure your C program takes in the necessary inputs and spits out those calculations. Good luck, darling!

Area of a semi circle: (pi*radius2)/2 square feet

Yes.
Calculate the area of a rectangle and of the semicircle separately, then add.
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
