1666m^2

Step-by-step explanation:

V=(pi * r^2 *h) /3

r=RT*cos(40)= 20*cos(40)=15.3

h=20*sin(40)=6.8

V=(3.14 * 15.3^2 * 6.8)/3=1666m^2

I hope this helps, have a good day

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

yes they are the same
