Answer:
Step-by-step explanation:
Given is the hexagonal pyramid.
We know the radius of the base is same as its side.
<u>Find the base area:</u>
- A = 3√3/2a²
- A = 3√3/2*6² = 54√3
<u>Given the height and radius, find the side of the lateral triangular faces:</u>
Each of 6 triangles have sides 10, 10 and 6 units.
<u>Find the area using heron's formula:</u>
- s = P/2 = (10*2 + 6)/2 = 13
- s - a = s - b = 13 - 10 = 3
- s - c = 13 - 6 = 7
![A = \sqrt{s(s-a)(s-b)(s-c)} =\sqrt{13*3*3*7} =3\sqrt{91}](https://tex.z-dn.net/?f=A%20%3D%20%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D%20%3D%5Csqrt%7B13%2A3%2A3%2A7%7D%20%3D3%5Csqrt%7B91%7D)
<u>Total surface area:</u>
Correct choice is B
Answer:
1. width is w. length is w + 26
2.
![w \times (w + 26) < 2040](https://tex.z-dn.net/?f=w%20%5Ctimes%20%28w%20%20%2B%2026%29%20%20%20%3C%202040)
3. the width must be less than 34
4. sure, if the width is 10, then the area is 360
Step-by-step explanation:
![w \times (w + 26) < 2040](https://tex.z-dn.net/?f=w%20%5Ctimes%20%28w%20%20%2B%2026%29%20%20%20%3C%202040)

Answer:
Volume of the cylinder is 75.43
Step-by-step explanation:
Volume of Cylinder is ![\pi r^{2} h](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20h)
where r is base radius = 2 and h is the height = 6
(22/7) × 2² × 6
= (22/7) × 4 × 6
= (22/7) × 24
= 528/7
= 75.43
