Looking at the attachment, we'll determine entire hexagon area with this formula:
area = apothem^2 *Number of sides * tan(180/n)
area = 17.32^2 * 6 * tan (30)
area = <span> <span> <span> 299.9824 </span> </span> </span> * 6 * 0.57735
area = <span><span><span> 1,039.16903184 </span> </span> </span>
Now we subtract the triangle area (16*20 = 320)
shaded area = <span> 1,039.16903184 -320 = </span> <span> <span> <span> 719.16903184 </span> </span> </span>

Answer:
Hi there!
Step-by-step explanation:
Your question was: 21*0.64 right?
Well, the answer to your question is 13.44
This is how we multiply;
21
X 0.64
________
84
+ 1260
_________
1344
(Don’t forget to place the decimal!)
So now we have 1344, let’s place the decimal!
=> the decimal should be placed here: 13.44
Hope this helps!
~Have a great day!~
If you have any questions feel free to ask!
(Just in case if you didn’t understand my explanation, I attached a picture..of how we are supposed to multiply “21*0.64”)
Answer:
- 1
Step-by-step explanation:
The product of the slopes of lines perpendicular to each other is - 1
Given y = 4x - 5 with slope 4
y = - x - 5 with slope -
then
4 × - = - 1 proving the lines are perpendicular
