Answer:
a-6b+4c
Step-by-step explanation:
a-{5b-[a-(3b-2c)+c-(a-2b-c)]}
a-{5b-[a-1(3b-2c)+c-1(a-2b-c)]}
a-{5b-[a+(-3b+2c)+c+(-a+2b+c)]}
a-{5b-[a-3b+2c+c-a+2b+c]}
a-{5b-[-b+4c]}
a-{5b+[b-4c]}
a-{5b+b-4c}
a-{6b-4c}
a+{-6b+4c}
5 buses is the answer pls mark me brainliest
V = 1/3 * pi * r^2 * h
d = 12
r = d/2
r = 12/2
r = 6
V = 1/3 * 3.14 * 6^2 * 8
V = 301.44
