what is the area of a triangle 8'. tall

with a 6". base, sitting on 1/2 a circle

area= 1/2 PI*radius^2+ 1/2 b*h

What is an equation for a shape with 4 sides the first is 2 ft ,3 ft , 6ft, and x the perimeter is 6

To find the area of the triangle, you need to know both the height and the base.

In this case, the height of the triangle is given as 8 feet, and the base is given as 6 inches.

However, there is an additional component mentioned which is "sitting on 1/2 a circle." It is not clear how the circle is related to the triangle and its dimensions. Could you please provide more information or clarify the relationship between the triangle and the circle?
