Answer:
Pretty sure it's the last one at the bottom.
<span>V = 1/3(3.14)r^2h
=1.046r^2h
Solving for V </span>
Y=-1/3+2 should be what you are looking for.
Answer:
103°
Step-by-step explanation:
The marked angles have the same measure, so ...
14x+7 = 12x +17
2x = 10 . . . . . subtract 12x+7
x = 5 . . . . . . . divide by 2
(14x +7)° = 77°
∠CEA is supplementary to the marked angles:
∠CEA = 180° -77°
∠CEA = 103°
Answer:
66
Step-by-step explanation:
The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D
