Answer:
<u>65.4 cubic inches</u>
Step-by-step explanation:
Formula for the volume of a cone :
<u><em>Volume (cone) = 1/3πr²h</em></u>
<u><em /></u>
=============================================================
Given :
⇒ diameter = 5 in. → radius = <u>2.5 in.</u>
⇒ height = <u>10 in.</u>
<u />
===========================================================
Solving :
⇒ Volume (cone) = 1/3 × π × (2.5)² × 10
⇒ Volume (cone) = 62.5π/3
⇒ Volume (cone) = <u>65.4 cubic inches</u>
All three angles in a triangle add up to 180 degrees.
Therefore, we should just add up all the angles given to us and set them equal to 180 :)
3x + 5x + (2x + 5) = 180
Now we just need to combine all the similar terms together (which is the 3x, 5x, and 2x):
10x + 5 = 180
Subtract 5 from both sides of the equation:
10x = 175
Now just divide by 10 on both sides to isolate the x and work out your value:
x = 17.5
Therefore, your final value of x is 17.5 :)
