X = 18 - 1/2 the answer is 18 of x/18
Answer:
150 degrees
Step-by-step explanation:
(Sorry, I know you don't want one but I posted this and then started editing it so hopefully you saw the answer already and I'm not delaying you or anything)
The interior of a quadrilateral always adds up to 360 degrees. y+80 = 180 degrees since they're on a straight line.
We have 3 angles: y = 100, 50, and 60.
360 - (100+50+60)
= 360 - 210
= 150
Answer: option D is the correct answer.
Step-by-step explanation:
The tower has a cone-shaped attic. Therefore, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Radius = 9 feet
Height = 18 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 18
Volume = 1/3 × 3.14 × 81 × 18
Volume = 1526.04 ft³
I believe the answer is C.
