Find the volume
v=
*(im not sure if this will help because it didn't help me)
Volume=1/3(base area)(height)
"The height of the pyramid h is the length of the segment from the vertex of the pyramid to the center of the base triangle. This plus the radius of the triangle and the intersection of two of the faces form a right triangle. The intersection is the hypotenuse of the triangle and the height can be calculated using the Pythagorean theorem."

will give the brainliest!
