The answer would be : Stopwatch
Answer:
5.9%
Step-by-step explanation:
V = 115.5 cubic yards
V (cone) = 1/3πr²h
just substitute given values to get:
r = 7/2 or 3.5
h = 9
V = π(3.5²)(9)/3
Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.
