V= 4/3 • 3.14 • radius to the 3rd power.
If you don't have the radius, you can find it by dividing the diameter by 2.
Hope this helps!
Answer:
x = 17
Step-by-step explanation:
in such a constellation (two beams from the same point of origin cut through the same circle) the relative relation between the segments of these beams to the overall length of the beam have to be the same :
7 × (7+x) = 8 × (8+13)
49 + 7x = 8 × 21 = 168
7x = 119
x = 17
Answer:
Let Tom's cards = x
Equation:
Neils Cards = x + 83 (Neil has 83 more cards)
x + 83 = 517 (Tom has 83 cards less than Neil)
x = 434
