Answer:
<h2>
V = 360π in³</h2>
Step-by-step explanation:
the formula for the volume of a cone of base radius r and height h is:
V = (1/3)(πr²)(h). Here, r = 6 in and h = 30 in. Then,
V = (1/3)(π)(6 in)²(30 in), or
= (1/3)π(36 in²)(30 in), or
V = 360π in³
The answer to this question is:

Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>We can also write it as:</u>
x-intercept is the point where y = 0
Put y = 0 in the above equation
![0=x^2-7\\\\Add \ 7 \ to \ both\ sides\\\\7 = x^2\\\\Take \ sqrt \ on \ both \ sides\\\\\pm \sqrt{7} =x\\\\x = \pm \sqrt{7} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=0%3Dx%5E2-7%5C%5C%5C%5CAdd%20%5C%207%20%5C%20to%20%5C%20both%5C%20sides%5C%5C%5C%5C7%20%3D%20x%5E2%5C%5C%5C%5CTake%20%5C%20sqrt%20%5C%20on%20%5C%20both%20%5C%20sides%5C%5C%5C%5C%5Cpm%20%5Csqrt%7B7%7D%20%3Dx%5C%5C%5C%5Cx%20%3D%20%5Cpm%20%5Csqrt%7B7%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
