Mathematics
1 answer:
telo118 [61]3 years ago

Answer:

314 m³

Step-by-step explanation:

The volume (V) of a cone is calculated using the formula

V = \frac{1}{3}πr²h

where r is the radius and h the perpendicular height

To find h use the right triangle from the vertex to the midpoint of the base and the radius.

Using Pythagoras' identity on the right triangle

where the slant height is the hypotenuse, then

h² + 5² = 13²

h² + 25 = 169 ( subtract 25 from both sides )

h² = 144 ( take the square root of both sides )

h = \sqrt{144} = 12, hence

V = \frac{1}{3}π × 5² × 12

   = π × 25 × 4 = 100π ≈ 314 m³

PLZ Answer ASAP!!!
Sliva [168]

Answer:

D. x = 3

Step-by-step explanation:

The only way we could get a line of symmetry through this figure is to use a vertical line.  The only way to get symmetry would be to put the vertical line though the point x = 3.  When we do that, we can see that the end points of the base are both one unit away from the line of symmetry.  The end points I'm talking about are the points at the coordinates (2, 4), and (4, 4)

Use an equation to find the value of kk so that the line that passes through the given points has the given slope. (4,−4), (k,−1
mina [271]
Hey there!
The formula for slope is:
(second y value - first y value) divided by (second x value - first value).
So we can solve in the reverse and plug in what we know to find the missing point, k.

(-1 - -4 = 3) / (k - 4) =3/4

Since the top value comes out as 3, that means we have to find out what value k has to be so that the bottom part of the fraction will equal 4, this number would be 8. (8,-1)

Your value of k is 8.

Hope this helps. :)

The highest land in Saskatchewan is Cypress Hills, at 1468m above sea level. Lake Athabasca shoreline at 65 m above sea level. E
uysha [10]

Answer:

Difference in elevation = 1,403 m

Step-by-step explanation:

Given:

Elevation of Cypress Hills = 1,468 m above sea

Elevation of Lake Athabasca = 65 m above sea

Find:

Difference in elevation

Computation:

Difference in elevation = Elevation of Cypress Hills - Elevation of Lake Athabasca

Difference in elevation = 1,468 m - 65 m

Difference in elevation = 1,403 m
