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.
How do you find sides of perimeter of triangle when area is given?
To find the sides of a triangle when only the area is given, you can use Heron's formula, which relates the area to the semi-perimeter and the lengths of the sides. First, denote the sides as (a), (b), and (c), and calculate the semi-perimeter (s = \frac{a+b+c}{2}). The area (A) can be expressed as (A = \sqrt{s(s-a)(s-b)(s-c)}). However, without additional information, such as the ratio of the sides or one side length, you cannot uniquely determine the side lengths from the area alone.
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.
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

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

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).
