D = 20 , v = 19
20v + 12d - 6v
= 20 (19) + 12 (20) - 6 (19)
= 380 + 240 - 114
= 620 - 114
= 506
When d = 20 and v = 19
20v + 12d - 6v = 506
Answer:
<h2>-2√3 + 2√15</h2>
Step-by-step explanation:
√3 (-2+√20) = √3×(-2) + √3×√20
= -2√3 + √3×√(4×5)
= -2√3 + √3×√4×√5
= -2√3 + √3×2×√5
= -2√3 + 2√15

Step-by-step explanation:
Wouldn’t it be 7*4/2? so the answer would be 14
Answer:
Yes it is is 392.9 m^3
Step-by-step explanation:
Volume of cylinder is π*r^2*h, π times radius squared times height.
Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.
