Inradius of Isosceles Triangle given Legs and Height Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inradius of Isosceles Triangle = (Height of Isosceles Triangle*sqrt(Legs of Isosceles Triangle^2-Height of Isosceles Triangle^2))/(Legs of Isosceles Triangle+sqrt(Legs of Isosceles Triangle^2-Height of Isosceles Triangle^2))
r_i = (h*sqrt(S_Legs^2-h^2))/(S_Legs+sqrt(S_Legs^2-h^2))
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Inradius of Isosceles Triangle - (Measured in Meter) - The Inradius of Isosceles Triangle is defined as the radius of the circle inscribed inside the Isosceles Triangle.
Height of Isosceles Triangle - (Measured in Meter) - The Height of Isosceles Triangle is the perpendicular distance from the base of the triangle to the opposite vertex.
Legs of Isosceles Triangle - (Measured in Meter) - The Legs of Isosceles Triangle are the two equal sides of the Isosceles Triangle.

STEP 1: Convert Input(s) to Base Unit

Height of Isosceles Triangle: 8 Meter --> 8 Meter No Conversion Required
Legs of Isosceles Triangle: 9 Meter --> 9 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_i = (h*sqrt(S_Legs^2-h^2))/(S_Legs+sqrt(S_Legs^2-h^2)) --> (8*sqrt(9^2-8^2))/(9+sqrt(9^2-8^2))

Evaluating ... ...

r_i = 2.51349382881987

STEP 3: Convert Result to Output's Unit

2.51349382881987 Meter --> No Conversion Required

FINAL ANSWER

2.51349382881987 ≈ 2.513494 Meter <-- Inradius of Isosceles Triangle
