The volume:
Pi x r^2 x h
V = pi x 12^2 x 7
V = 1008pi units^3
The answer would be a
hope it helps.
153=9*17=3*3*17
so the prime factorization is 3*3*17 (also can be written

*17)
If a² + b² = c², then the triangle is <u>right</u>.
So we have (8)² + (11)² <u>?</u> (13)²
(8)² is 64, (11)² is 121, and (13)² is 169.
So we have 64 + 121 <u>?</u> 169
64 + 121 is 185 and we can see that 185 > 169.
This triangle would not be a right triangle.
In fact, it would be an acute triangle.
So no, it's not a right triangle.
