WATER TOWER One of the largest sphere water towers in the country is located in Edmond, Oklahoma. It is 218 feet tall and holds
Fudgin [204]

Answer: The radius of the new water tower is approximately 21 ft^3

Step-by-step explanation:

  So we know the volume  of the Water Tower is 66840 ft^3   and the new one's volume will hold 3/5 as much.  so you will multiply  66840 by 3/5 to find the volume of the new one.

66840 * 3/5 = 40104   so the new water tower will hold 40104 cubic feet of water.

Now to find the radius we will use the formula  v= 4/3\pir^3

40104 =  4/3 * \pi* r^3

 40104=  4.1887* r^3

r= 21

Calcular: E = (sec245o + tg45o) ctg37o - 2cos60o
Vlada [557]

Answer:

-2.813

Step-by-step explanation:

Se simplifica inicialmente la fórmula en términos de las funciones trigonométricas fundamentales (Initially, the formula is simplified in terms of fundamental trigonometric functions):

(\sec 245^{\circ} + \tan 45^{\circ} )\cdot \cot 37^{\circ} - 2\cos 60^{\circ}

\left(\frac{1}{\cos 245^{\circ}}+\frac{\sin 45^{\circ}}{\cos 45^{\circ}}  \right)\cdot \left(\frac{\cos 37^{\circ}}{\sin 37^{\circ}} \right) - 2\cdot \cos 60^{\circ}

(-2.366 + 1 )\cdot (1.327) - 1

-2.813
