What is the volume of a cone with a diameter of 30 feet and a hight of 60 feet​
ivolga24 [154]

Answer:

4500\pi ft^{3}or 4712.39ft^{3}

What we need to know: The formula for the volume of a cone is: V=\pi r^{2} \frac{h}{3}

So we are solving for V

Step-by-step explanation:

1) Radius is half of diameter r=30/2 thus, your radius is 15

2) you then have all your variables so you can start plugging values into your equation:

r=15 h=60

V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi

This would be your exact answer but if you are solving for a rounded answer it would be

V~4712.39ft^{3}

Find EXACT area of regular hexagon (keep in radical form)
pickupchik [31]

Answer:

1. 24\sqrt{3}   2. 162\sqrt{2}

Step-by-step explanation:

1. The area of a hexagon is A = \frac{3\sqrt{3} }{2} a^{2}

Here our a is 4, so plugging in 4 to our equation gives \frac{3\sqrt{3} }{2} (4^{2}) which simplifies to 24\sqrt{3}

2. The area of an octagon is 2\sqrt{2} r^{2}

Here our r is 9, so plugging in 9 to our equation gives 2\sqrt{2} (9^{2} ) which simplifies to 162\sqrt{2}
