Who discover herons formulas?
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.
What is formula of perimeter of semi circle?
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)
What is the answer to finding the area of 4 semi-circles with the diameter of 10 centimeters?
-6
How do you find the area of a rectangle with a semi circle attached to it?
Calculate the area of a rectangle and of the semicircle separately, then add.
How do you find the perimeter for a semi circle?
Its perimeter is half of its circumference plus its diameter
What is the semi-perimeter of a triangle with side lengths 11 61 and 60?
Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.
What is the Perimeter of semicircle and quadrant circles?
The semi-circle is 0.5 X pi X diameter + diameter The semi-circle is 0.5 X pi X diameter + diameter

How do you calculate the ellipse area?
Area = pi*a*b where a and b are the semi-major and semi-minor axes.

How do you calculate square footage of semi circle?
Area of a semi circle: (pi*radius2)/2 square feet
Is the the semi-circles of two congruent circles always congruent?
Yes.

Work out the perimeter of the semi-cirle when diameter is 15cm?
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).
How do you find the area of a rectangle with a semi circle attached to it?
Calculate the area of a rectangle and of the semicircle separately, then add.
What is the Memphis?
circles, squares, rectangles mainly... but the odd semi circles etc...
