What is the volume of this cone?

olchik [2.2K]

Answer:

The volume of the cone is approximately 453.0 cm³

Step-by-step explanation:

The volume of a cone is one third that of a cylinder with the same height and radius. That gives us 1/3 πr²h, where r is radius and h is height.

However, we are not given the height of the cone, but the side length. We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length. You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:

$a^2 = b^2 + c^2$

So we can find the height of the cone with that:

$10.8^2 = 7.4^2 + h^2\\h^2 = 10.8^2 - 7.4^2\\h^2 = 116.64 - 54.76\\h^2 = 61.88\\h = \sqrt{61.88}\\h \approx 7.9$

Now that we have the cone's height, we can solve for its volume:

$v = \frac{1}{3} \pi r^2 h\\v = \frac{1}{3} \pi \times 7.4^2 \times 7.9\\v = \frac{1}{3} \pi \times 54.76 \times 7.9\\v = \frac{1}{3} \pi \times 432.6\\v = \pi \times 144.2\\v \approx 453.0 cm^3$

I only need number 11 in the picture please help and show work

IgorLugansk [536]

Answer:

1 = 115°

2 = 115°

3 = 65°

Step-by-step explanation:

P=65, so S (3) =65

360-65-65=230

230/2=115

Q (1) = 115

R (2) = 115

Answer: 21 shifts

Explanation:

If you want to have nurses on duty 24 hours a day 8 hours at a time, first divide 24 by 8. You get 3, which is the amount of shifts per day. Then multiply 3 by the amount of days in a week, 7, and get 21 shifts per week. Hope this helps!
