Diameter of Fourstar given Edge Length and Inner Angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Fourstar = Edge Length of Fourstar*sqrt(2)*(sqrt(1+cos(Inner Angle of Fourstar))+sqrt(1-cos(Inner Angle of Fourstar)))
D = l_e*sqrt(2)*(sqrt(1+cos(∠_Inner))+sqrt(1-cos(∠_Inner)))
This formula uses 2 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
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

Diameter of Fourstar - (Measured in Meter) - The Diameter of Fourstar is the distance between the opposite spike tips of the Fourstar.
Edge Length of Fourstar - (Measured in Meter) - The Edge Length of Fourstar is the length of any edge of the Fourstar shape from one end to other end.
Inner Angle of Fourstar - (Measured in Radian) - The Inner Angle of Fourstar is the unequal angle of the isosceles triangle that attached to the square or the angle between the edges which form the triangular spike, of the Fourstar.

STEP 1: Convert Input(s) to Base Unit

Edge Length of Fourstar: 5 Meter --> 5 Meter No Conversion Required
Inner Angle of Fourstar: 75 Degree --> 1.3089969389955 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = l_e*sqrt(2)*(sqrt(1+cos(∠_Inner))+sqrt(1-cos(∠_Inner))) --> 5*sqrt(2)*(sqrt(1+cos(1.3089969389955))+sqrt(1-cos(1.3089969389955)))

Evaluating ... ...

D = 14.0211476929993

STEP 3: Convert Result to Output's Unit

14.0211476929993 Meter --> No Conversion Required

FINAL ANSWER

14.0211476929993 ≈ 14.02115 Meter <-- Diameter of Fourstar
