Answer:
The approximate volume is 
Step-by-step explanation:
we know that
The exact volume of the cylinder is

so
To find the approximate volume of the cylinder, substitute the term
by the approximate value of
and then multiply
so

56/8=7. so we multiply 7 by 7.7*7=49; the helicopter is 49 in. wide
