V = pi x r^2 x h
V = 3.14 x 6^2 x 13
V = 1469.52
Answer:
sin x = cos y
Step-by-step explanation:
sin theta = opp / hyp
cos theta = adj / hyp
First find the hyp
a^2 + b^2 = c^2 from the Pythagorean theorem
5^2+12^2 = hyp^2
25+144= hyp^2
169= hyp^2
Taking the square root of each side
sqrt(169) =sqrt(hyp^2)
13= hyp
sin x = opp / hyp=5/13
sin y = 12/13
cos x = 12/13
cos y = 5/13
sin x = cos y
6 inches the night is I look it up on edgnuity
We know that
1 cubic yards equals to--------------> 27 <span>cubic feet
then
</span><span>I apply a rule of three
if </span>1 cubic yards ------------------- 27 ft³
X----------------------------------> 648 ft³
X=648/27=24 cubic yards
the answer is 24 cubic yards
Step-by-step explanation:
Before we proceed, we must understand that we are dealing with a system of right angled triangles.
There are two types of right angle triangles';
45° - 45° - 90° 30° - 60° - 90°
In 45° - 45° - 90°, the adjacent is equal to the opposite
30° - 60° - 90°, there are three different sides
The longest side faces 90°, the shortest side will face the smallest angle and the intermediate will face 60°
A.
To find AB, use Pythagoras theorem;
AB² = AC² + BC²
AB² = 13² + 4²
AB² = 169 + 16 = 185
AB = √185 = 13.6
AB = 13.6
Angle A = 30°
Angle B = 60°
B.
AB² = BC² + AC²
The unknown is AC;
AC² = AB² - BC²
AC² = 5² - 4²
AC² = 9
AC = √9 = 3
Angle A = 60°
Angle B = 30°
C.
AB² = AC² + BC²
Insert the parameters and find AC;
AC² = AB² - BC²
AC² = 11² - 4.4²
AC² = 101.64
AC = √101.64
AC = 10.1
Angle A = 30°
Angle B = 60°
AC = 13
