Answer:

244.92 ft^2

Step-by-step explanation:

Find out the surface area of 1 fence post.

It has 2 circular parts (a bottom and a top)

r = d / 2

r = 1 / 2

r = 0.5 feet.

Area = 3.14 * 0.5^2

area = 3.14 * 0.25

Area = 0.785

Each post has 2 such shapes. 2 * 0.785 = 1.57

There are 12 posts with areas of 1.57 on the bottom and top  = 18.84 ft^2

Find the area of the long part of the post

h = 6 feet

circumference = 2* pi * r

circumference = 2* 3.14 * .5

circumference = 3.14

The height is 6 feet.

The area of the body of the pole 6 *circumference = 6 * 3.14 = 18.84 ft^2

There are 12 poles.

Total area = 12 *18.84 ft^2 =  226.08

Total area = 12 bodies + 24 ends

Total area = 226.08 + 18.84

Total area = 244.92

One angle of a triangle measures 36.5 degrees. What is the measure of the smaller angle?
Sunny_sXe [5.5K]

The final answer would depend in the type of triangle we are analyzing, however here are the possible outcomes:

1.) If it was a right triangle, 36.5 would be the smaller angle.

2.) It cannot be an equilateral triangle since all angles would be 60°.

3.) In a isosceles triangle, 36.5° would be the smaller, since the others would be 72°.

4.) In an scalene triangle it cannot be determined unless we had 2 angles since in that kind of triangle all angles can be different.

5.) In an acute triangle, 36.5° would be the smaller angle.

6.) In an obtuse triangle it cannot be determined unless we had 2 angles, since it can have highly acute angles.
