How do you solve 216 - 202?? -explained-

Serhud [2]

Answer: 216 - 202 = 14

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

OleMash [197]

Answer:

Diameter of tank = 19.5 ft

Step-by-step explanation:

Volume of cylinder = Base area x Height.

Base area = Area of circle

$\texttt{ Area of circle}=\frac{\pi d^2}{4}$

Height = 20 ft.

Volume of tank = 6000 cubic feet .

$\texttt{ Volume of cylinder = Base area x Height.}\\\\6000=\frac{\pi d^2}{4}\times 20\\\\d^2=381.97\\\\d=19.5ft$

Diameter of tank = 19.5 ft

Need help solving this

DedPeter [7]

Answer:

x = (√21)/2

Step-by-step explanation:

The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. That means the middle-length side is (√3)/2 times the length of the longest side.

x = (√3)/2·√7

$\boxed{x=\dfrac{\sqrt{21}}{2}}$
