162 cow-days

Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.

I will assume that the first one is the one with radius 16 and height 40
2nd is radius 7 and height 26



1. v=hpir^2
v=40pi16^2
v=40pi256
v=10240pi cubic inches
3rd option





2.
v=hpir^2
v=26(3.14)7^2
v=26(3.14)(49)

What is the sum of the exterior angles of a 54-gon?
oksian1 [2.3K]

Answer: The sum of the exterior angles of a 54-gon should be 360°.

Step-by-step explanation:

A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.

The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.

A 54-gon is a polygon with 54 sides.

Therefore , the sum of the exterior angles of a 54-gon should be 360°.
