87. Is this triangle a right triangle?
2 answers:
Answer:
Step-by-step explanation:
39²=1521
80²=6400
39²+80²=1521+6400=7921
87²=7569
7921≠7569
so it is not aright angled triangle.

Answer:
Step-by-step explanation:
Givens
d = 3"
h = 1 inch
pi = 3.14
Formula
V = pi r^2 h
Solution
r = d/2
r = 3/2 = 1.5
V = 3.14 * 1.5^2 * 1
V = 3.14 *2.25
V = 7.065
X=16
Y=-6
