Step-by-step explanation:
V = 4222.30053 m3
Answer:12
20 cm
Shadow of vertical poles : 6m ; 15m
Length of poles : 8cm ; h
8cm long pole = shadow length, 6m
h cm long pole = shadow length, 15 m
Using cross multiplication :
8cm * 15 m = h cm * 6m
120 = 6h
h = 120 / 6
h = 20 cm
Height of second pole = 20cm
9+x<12
add 9 to an unknown number.
9+x
use the < less than symbol (instead of an equal sign) and write 12.
