how do you find the area of an equilateral triangle inside a circle

Question

need to find the area of an euilateral traingle inside a circle with radius of 6

Answer 1

equlateral triangel inside serkel wen input=serkel radius

all angels=60 deg

hite=side*kosine(30)=side*root(3)/2

area=base*hite/2=side*side*root(3)/4 =0.4330127*side*side

senter av serkels (inside & outside) is on vertikal line thru triangel top &

midpoint av base

distans from senter tu base=radius av inside serkel

Draw lines from senter tu 3 korners av triangel...get 3 idenikal wek triangels

(from senter tu points av equilateral triangel=outside serkel radius)

inside serkel radius=(1/2) outside serkel radius=(1/2)Radius

base=(side/2)=(outside radius)*kosine(30 deg)=1.7320508*Radius

tri area=(hite*base/2)=(1.5*outradius)*(root(3)*outradius/2

=1.29903106*(out rad)*(out rad)
