Answer:
Step-by-step explanation:
The lateral area that Rachel needs to cover is 21 inches squared. You find this by first finding the area of one triangular side. To do this, you must half the base of one side, so it makes 2, and multiply it by the height, which gets you to 7. Then, you must half this, as the formula for the area of a triangle states, and then multiply this by two as you at first found the area of only HALF the triangle. This should still get you to 7. Now, there are three lateral sides, not including the base, so you must multiply 7 by 3. This gets you 21.
It would be 3,600 - 30 = 3570

Answer:
x = 4
Step-by-step explanation:
TW = 3
WU = TU - TW = x + 7 - 3 = x + 4
CW = x
VW = 6
By the property of intersecting chords inside a circle, we have:
TW * WU = CW * VW
3(x + 4) = x * 6
3x + 12 = 6x
12 = 6x - 3x
12 = 3x
12/3 = x
4 = x
x = 4
6in×2=12inches and 2/5×2=0.8 so the answer would be 12.8
