Answer:
1385.28 m²
Step-by-step explanation:
apothem = √16² - 8² = √256 - 64 = √192 = 13.86
Base area = 3 x 16 x 13.86 = 665.28
6 side area = 3 x 16 x 15 = 720
surface area = 665.28 + 720 =1385.28
Answer:
9
Step-by-step explanation:
5x+3x-3= 8x+16-10
5x+3x-8x=16-10+3
8x-8x=9
= 9
7/1, I think that’s right
If y = 2x, then y/x = 2. The constant of proportionality is 2.
Answer:
- 8

Step-by-step explanation:
<u>We know that:</u>
<u>We can find one side by distance formula:</u>
- a =

- a =

<u>Then the perimeter is:</u>
- P = 4*2
= 8
