7/4pi multiplied by 180/pi give you about 97 degrees when you calculate it.
The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)
The answer is 3/8
hope it helps
please mark as brainliest i need one more
Yes, I do like your pfp it looks very cool
Based on observation, in this polyhedron, there are a total of six vertices, nine edges, and five faces.
<h3>What are vertices?</h3>
In geometry, this refers to the point where two line meet. In this case, the vertices are A, B, C, D, E, F for a total of six vertices.
<h3>What are the edges?</h3>
This term refers to line segments, for example the line between B and C is an edge. Based on this, there are nine edges in this shape.
<h3>What are faces?</h3>
This refers to flat surfaces; in this, case the total of flat surfaces are five.
