Question 776992
{{{A=(1/2)b*h}}}, {{{A=pi*r^2}}}

Area is calculable and the only actual unknown is h.
b = base length of triangle
r = radius of circle
A = area of both triangle and circle.
h = height of triangle.  UNKNOWN.


Equate the equal areas.
{{{(1/2)bh=pi*r^2}}}
Apply Multiplicative Inverses...
{{{highlight(h=(2/b)pi*r^2)}}}___________________Solved symbolically.


Substitute the values to find h value.
