Answer:
you need the formula for the cone , Korc
Step-by-step explanation:
formula for cone = 
*π*
*h
they tell us that the diameter is 8 so r = 4
and that h = 9
volume of cone = *π*
*9
VoC = 150.796
VoC = 150.8 ( to the nearest 10th)

Answer:
A triangle is normally 180 degrees only.
Step-by-step explanation:
So, you have one 90 degree angle, and on 42.7 degree angle. Add those up to 132.7. Now, you would subtract that from 180, meaning that the answer is A, 47.3.
Good luck :DD
Answer:
x = 16
m<Y = 34°
Step-by-step explanation:
∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:
<X = <Z
(6x - 23)° = (4x + 9)
Solve for x
6x - 23 = 4x + 9
Collect like terms
6x - 4x = 23 + 9
2x = 32
Divide both sides by 2
x = 16
m<Y = 180° - (m<X + m<Z) (sum of ∆)
m<Y = 180 - ((6x - 23) + (4x + 9))
Plug in the value of x
m<Y = 180 - ((6(16) - 23) + (4(16) + 9))
m<Y = 180 - (73 + 73)
m<Y = 34°
