How do you mathematically find the area of a triangle?
The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
How is the area of a circle calculated?
The area of a circle is pi times the radius squared (A = π r²).
How do I calculate the circle of a triangle?
Given A, B, and C as the sides of the triangle and A as the area, the formula for the radius of a circle circumscribing a triangle is r = ABC / 4A and for a circle inscribed in a triangle is r = A / S where S = (A + B + C) / 2.
What is the area of a square inscribed in a circle?
We know the area of the square with side a cm is given by a2 cm2. Thus, the area of the square inscribed in a circle of radius x cm is 2×2 cm2. Note: Diameter of the circle is equal to double of the radius of the circle. Diagonal of a square inscribed in a circle is equal to the diameter of the circle.
How do find area?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
What are all the formulas for a circle?
Formulas Related to Circles
|Diameter of a Circle||D = 2 × r|
|Circumference of a Circle||C = 2 × π × r|
|Area of a Circle||A = π × r2|
What is an area formula?
L is the length, W is the width and H is the height. A is the area of the base, h is the height. Perimeter, Area, and Volume.

|Triangle||A=√s(s−a)(s−b)(s−c)where s=a + b + c2||a, b, and c are the side lengths and s is the semiperimeter|
How do you find the area and circumference of a circle?
How to find the area of a circle from the circumference?
- Divide the circumference by π.
- Divide the result by 2 to get the circle’s radius.
- Multiply the radius by itself to get its square.
- Multiply the square by π, or 3.14 for an estimation.
- You found the circle’s area from the circumference.
What is the angle of this triangle?
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
What is the radius of a triangle?
Calculating the radius Its radius, the inradius (usually denoted by r) is given by r = K/s, where K is the area of the triangle and s is the semiperimeter (a+b+c)/2 (a, b and c being the sides).
What is the radius of the circle circumscribing an isosceles triangle?
Problem Answer: The radius of the circle circumscribing an isosceles right triangle is 12.73 m.
