What’s the volume?<br> someone please help
bazaltina [42]

Answer:

17734.55 inches cubed. If you found this helpful, love the answer! Thank you :D

Step-by-step explanation:

Very simple. We find the area of the circle, A=Pi Radius Square.

So 3.14 (15x15)

A≈706.86

The bottom shape is 706.86x24=16964.64

The top is a cone, meaning its V≈3769.91

So 3769.91+16964.64=17734.55

In the diagram, m∠8=4x°, m∠7=30°, and m∠9=(6x−20)°. Find the value of x.<br><br> x= ???
svetoff [14.1K]

Answer:

x=25

Step-by-step explanation:

we know that

The <u><em>triangle external angle theorem</em></u> states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles

In this problem

m∠9=m∠7+m∠8

substitute the given values

(6x-20)\°=30\°+4x\°

solve for x

6x-4x=30+20\\2x=50\\x=25
