Volume of the cone is 117.5 π ft³

<u>Step-by-step explanation:</u>

Lateral area of the cone = πrs

s is the slant height = 15 ft

From the above formula, we can find the radius as, 5 ft.

Volume of the cone = π r² h/3

s = √ (5²+ h²)

Squaring on both sides, we will get,

s² = 15² = (5² + h²)

15² - 5² = h²

225 - 25 = 200 = h²

h = √200 = 14.1 ft

Volume = π × 5² × 14.1 / 3 = 117.5 π ft³

Wind farms are a source of renewable energy found around the world. If a turbine generates 500kW in a 10m/s wind, how much power

Annette [7]

<span>Wind farms are composed of tens of wind mills that us electric generator to harness the power of the wind. The power that comes out of the electric generators should be proportional with the force or the wind which is also proportional to the speed of the wind. Considering that a 10 m/s generates 500 kW, than a 12 m/s wind should generate somewhere around 600 kW.</span>

Karen, James, Frank, and Dan were left an inheritance by their late grandfather. If Karen receives one-eighth of the inheritance

pashok25 [27]

Count what fraction receive Karen, James and Frank in total:

since

Karen receives - $\frac{1}{8}$ ,

James receives - $\frac{1}{4}=\frac{2}{8}$ ,

Frank receives - $\frac{3}{8}$ ,

then $\frac{1}{8} +\frac{2}{8} +\frac{3}{8} =\frac{1+2+3}{8}=\frac{6}{8} =\frac{2\cdot 3}{2\cdot 4} =\frac{3}{4}$ .

All inheritance is the whole 1, then for Dan remains $1-\frac{3}{4} =\frac{4}{4} -\frac{3}{4} =\frac{4-3}{4} =\frac{1}{4}$ .

Answer: Dan receives one quarter of the inheritance.

An Olympic sized swimming pool is filled with 660,253 gallons of water. One third of it is left every hour. How much water will

Marina CMI [18]

Answer:

None

Step-by-step explanation:

If 1/3 is left every hour then it would then after 3 hours wouldn't it be gone? Most would assume if only a third of the water is left every hour then after three hours there would be either of two answers if the question was written correctly: one third because they refilled it on the 2nd hour or none because it wouldn't even last two hours

Will mark brainliest to whoever answers correctly first!!!

To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
