Answer: The first option, 52 ft.

Step-by-step explanation:

The data we have is:

The diameter of the lawn is 100ft.

Between the two pats, we have a 60° angle, so we want to calculate the distance between both paths, walking around the circle, this would be the length of the arc of 60°.

Now, first, we know that the perimeter of the circle is equal to 2*pi*radius.

So a section of the perimeter can be calculated as:

L = Angle*radius.

But we need to write the angle in radians.

We know that 180° = pi = 3.14

then (60°/180°)*3.14 = 1.04

60° is equivalent to 1.04 radians.

Now, we have the diameter of our circle, and we know that the radius is equal to half the diameter, so if d = 100ft, r = 100ft/2 = 50ft.

Then the length of the arc is:

L = 1.04*50ft = 52.3 ft

Then the correct answer is the first one (where the result is rounded to the next whole number, 52 ft.)

Find the volume of a right circular cone that has a height of 11.9 ft and a base with a radius of 16.3 ft. Round your answer to
vivado [14]

Answer:

3311.36ft^3

Step-by-step explanation:

Given data

Height h= 11.9ft

Radius=16.3ft

The expression for the volume of a cone is given as

Volume= 1/3πr^2h

substitute

Volume=1/3*3.142*16.3^2*11.9

Volume= 1/3*3.142*265.69*11.9

Volume= 1/3*9934.095962

Volume=3311.36ft^3

Hence the volume is 3311.36ft^3

which of the following expresses the coordinates of the foci of the conic section shown below? (x-2)^2/4+(y+5)^2/9
elena55 [62]

Step-by-step explanation:

\frac{(x - 2) {}^{2} }{4}  +  \frac{(y + 5) {}^{2} }{9}  = 1

This is the equation of the ellipse. Since the denominator is greater for the y values, we have a vertical ellipse. Remember a>b, so a

The formula for the foci of the vertical ellipse is

(h,k+c) and (h,k-c).

where c is

Our center (h,k) is (2, -5)

{c}^{2}  =  {a}^{2}  -  {b}^{2}

Here a^2 is 9, b^2 is 4.

{c}^{2}  = 9 - 4

{c}^{2}  = 5

c =  \sqrt{5}

So our foci is

(2, - 5 +  \sqrt{5} )

and

(2, - 5 -  \sqrt{5} )
