The answers would be 1 and 5.
Surface Area of the cylinder is 6x² + 83x - 58 cm²
Step-by-step explanation:
- Step 1: Given surface area of the cylinder, A = 23r + 2rh. Here, r = (3x - 2) and h = (x + 3)
⇒ A = 23(3x - 2) + 2(3x - 2)(x + 3)
⇒ A = 69x - 46 + (6x² + 18x - 4x - 12)
⇒ A = 6x² + 83x - 58 cm²
Answer:
Step-by-step explanation:
<u>Factorize both numbers:</u>
- 900 = 2*2*3*3*5*5
- 270 = 2*3*3*3*5
<u>Common factors are:</u>
<u>So HCF is:</u>
- HCF(900, 270) = 2*3*3*5 = 90
Answer:
20
Step-by-step explanation:
The number of combinations of 6 points taken 3 at a time is ...
6!/(3!·(6-3)!) = 6·5·4/(3·2·1) = 5·4 = 20
___
If you number the points 1–6, the points of the 20 triangles will be ...
123 124 125 126 134
135 136 145 146 156
234 235 236 245 246
256 345 346 356 456
If it’s rotating around something, it’s most likely a cylinder I believe
