C kinetic energy. As it loses potential energy, it gain kinetic energy
(5)(3x)+(5)(4)+(5)(-x)
15x+20-5x
Answer: 10x+20
Answer:
218
Step-by-step explanation:
first find the area of the circle-

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

Now I know the height is 12. Find the area of the triangle

subtract the area of the triangle from the area of the circle
314-96=218
Answer:
V = 1385.44
Step-by-step explanation:
The equation for volume is V = π r 2 h! Where V = volume, r = radius <em>(half the diameter)</em>, and h = height. Now lets substitute what we know into this equation!
<em>Since we are giving the diameter (14) we must divide by 2 to find the radius.</em>
14 ÷ 2 = 7
Radius = 7
Height = 9
V = ?
Time to plug these values in!
V = π
(9)
<em>We have to distribute </em><em>pi to 7 square that term </em><em>and then </em><em>multiply the value by 9</em><em>. </em>
<em />
V = 1385.44
