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!

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer:

24pi or letter c
