Answer:
V = 942mm^3
Step-by-step explanation:
To find the volume of a cone you have to use this equation:

V = [(3.14)(10^2)(9)] /3
V = [(3.14)(100)(9)] /3
V = [2826] /3
V = 942mm^3
Answer:
theta = 180 -(A +B)
Step-by-step explanation:
The sum of the angles of a triangle is 180
theta + A + B = 180
solve for theta
Subtract ( A + B) from each side
theta +A+B -(A +B) = 180 -(A +B)
theta = 180 -(A +B)
Yes that is correct to my knowledge
