Answer:
100π
Step-by-step explanation:
We have to find the height. Since we have the base and hypotenuse of the triangle, we can use the Pythagorean Theorem to find the side. We have c^2 - a^2 = b^2; 13^2 - 5^2 = 144; sqrt144 = 12. The height is 12 and the radius is 5, so using V = (1/3)πr2h, we get (1/3)π(25)(12) = 100π

Please see the attached images for full solution.
For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.
Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.
Answer:
a-b = 2a
a-b = -2b
Step-by-step explanation:
a+b = 0
Subtract b from each side
a+b - b=0-b
a = -b
a-b =
Replace a with -b
-b -b= -2b
a = -b
Divide by -1
-a =b
or replace b with -a
a - (-a)
a+a
2a
