Answer:
With speed of 18 feet per second the distance between the twins change.
Step-by-step explanation:
v1 is 10
v2 is -8
So, the difference is (10)-(-8)
which is 18.
A right circular cone has a circle as its base.
All answers that have B = l * w cannot be correct as that is the area of a rectangle, not a circle.
The area of a circle is A = pi r^2, so you need B = pi r^2 in the formula.
The only formula that is correct is choice D. V = 1/3 Bh, where B = pi r^2
21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
The first angle is 25 degrees
25+75=100
100-20=80
100+80=180
