Answer:
Step-by-step explanation:
Identity property of multiplication: Any number times 1 (unity) is the number itself. 7 times 1 is 7, the number with which we started.
V = (pi) * r^2 * h
h = 7
V = 252(pi)
252(pi) = r^2 * 7
252(pi) / 7 = r^2
36(pi) = r^2
sqrt 36(pi) = r
6 = r <==== radius is 6 cm
15-3b=63
subtract 15 from both sides
-3b=48
divide -3 from both sides
b= -16
