Answer:
12(6+9m)
therefore we multiple the 12 by the numbers in the blaket
72+10m
that's the correct answer
Answer:
Step-by-step explanation:
base=42 m
height=h=?
base angle θ=60°
tan 60=h/42
h=42tan 60=42√3≈72.75 m
height of taller building=135+42√3 m≈135+72.75≈207.75 m≈208 m
Volume = pi * radius^2 * height
= 3.14 * 5^2 * 13
= 3.14 * 25 * 13
= 1020.5
