Perimeter is 36. This is because the radius and side lengths are the same in a regular hexagon.
Are is roughly 93.53.
-- Measure the length of the box.
-- Measure the width of the box.
-- Measure the height of the box.
-- Make sure all 3 measurements are in the same units.
-- Multiply (length) x (width).
-- Take that answer and multiply it by (height).
-- You now have the volume of the box.
The total area of the blades is the area of a triangle multiplied by 4.
We have then:
Where,
b: base of the blades
h: height of the blades
Substituting values we have:
Doing the calculation we have that the area of the blades is given by:
Answer:
The total area of the blades is:
Answer:
2.79
Step-by-step explanation:
Given
With reference angle 21°
hypotenuse (h) = 3
base (b) = x
Now
cos 21° = b / h
0.93 = x / 3
x = 0.93 * 3
x = 2.79
Hope it will help :)
The answer is b. 1/27
3^-3=1/27 and 3^4=81. 1/27×81=3. 3×3=9. 3^-5=1/243. 1/243×9= 1/27. The answer is b. 1/27.
