A FISH TANK AT AN AQUARIUM HAS A VOLUME OF 1568 CUBIC FEET AND A DEPTH OF 8 FEET. IF THE BASE OF THE TASNK IS SQUARE WHAT IS THE

LENGHT OF SIDE OF THE TANK
Mathematics
1 answer:

8 0

Answer:

14 feet

Step-by-step explanation:

The volume is basically length * width * height

The depth can be taken as height, which is 8

Now, since the base is a square, the length and width are both x, so we can write:

Volume = length * width * height

1568 = x * x * 8

1568/8 = x^2

196 = x^2

x = Sqrt(196)

x = 14

The length of the side of the tank is 14 feet

  • Sum of Angles in a Quadrilateral: 360

Step-by-step explanation:

<u>Step 1: Set up</u>

75 + 120 + 90 + ∠4 = 360

<u>Step 2: Solve</u>

  1. Add:                                                                                                                   285 + ∠4 = 360
  2. [Subtraction Property of Equality] Subtract 285 on both sides:                   ∠4 = 75

What is the best approximation for the circumference of a circle with a diameter of 300 feet
garri49 [273]

Answer:

The answer is C=942.48

Step-by-step explanation:

You would figure this out by using the formula C=2πr.

So let's break this down.

Circumference (C) equals (=)  pi (π) times 2 times the radius of the circle.

Since the problem gave you the diameter which is the length from one side of the circle to the other, you have to divide the diameter in half. Which would give you a radius of 150.

Taking the 150 you would multiply 10*2*π.

Which would give you....(drumrollllll)

C=942.48

I hope this helps!!

p.s. have any more questions? Post them and comment the link!♥, Sadie
