Answer:
B= 52 pie m^3
Step-by-step explanation:
vol of a cylinder = pie*r^2× h
vol of a cone = 1/3 × pie*r^2×h
......vol of a cone with d same base nd height

Answer:
x = -1, 1, -5 , 5.
Step-by-step explanation:
x4 – 26x2 + 25 = 0
Factoring:
(x^2 - 25)(x^2 - 1) = 0
So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.
x^2 - 1 gives x^2 = 1 and x = +/- 1.
