The surface of a polyhedron can be found by using the following equation:<span>1. Draw a net of the polyhedron.
</span><span>2. Calculate the area of each face.<span>
</span></span><span><span>3. Add up the area of all the faces.</span></span>
R = (2s - 6t + 5)/2
2R = 2s - 6t + 5
2s = 2R + 6t - 5
s = (2R + 6t - 5)/2
Answer:
A. 31.4 in.
Step-by-step explanation:
Formula for the circumference:
C = dπ (d = 2r)
Therefore:
C = 10π
C = 10 · 3.14
C = 31.4 in.
