Inradius of Nonagon given Perimeter Calculator

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Inradius of Nonagon - (Measured in Meter) - Inradius of Nonagon is defined as the radius of the circle which is inscribed inside the Nonagon.
Perimeter of Nonagon - (Measured in Meter) - Perimeter of Nonagon is the total distance around the edge of the Nonagon.

STEP 1: Convert Input(s) to Base Unit

Perimeter of Nonagon: 70 Meter --> 70 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_i = P/(tan(pi/9)*18) --> 70/(tan(pi/9)*18)

Evaluating ... ...

r_i = 10.6846344089902

STEP 3: Convert Result to Output's Unit

10.6846344089902 Meter --> No Conversion Required

FINAL ANSWER

10.6846344089902 ≈ 10.68463 Meter <-- Inradius of Nonagon

(Calculation completed in 00.004 seconds)
