Answer: The correct answer is 10 piranhas.
Step-by-step explanation:
To calculate the total Volume of a cylinder we have to use the following formula:
Volume = Area * Height
Area = π * r² , where r= radius
The diameter is always the twice the radius so the diameter is 4 feet in this case and the radius is 2 feet so the area is
Area= 3.1416 * (2*2)
Area = 3.1416 * 4
Area = 12.5664 square feet
Volume = 12.5664 (area) * 1.25 (height).
Volume = 15.708 cubic feet
Each piranha needs 1.5 cubic feet so we have to divide the total Volume by the volume that each piranha needs
15.708/ 1.5 = 10.472 or ten pirahnas because we can't put a fraction of a piranha in the tank.
Answer:
178 chairs
Step-by-step explanation:
(something) rows of (something) columns always means to multiply. So, let's multiply 8 x 23:
8 × 23 = 184
Now, since the workers removed 6 of the chairs, there are 6 less chairs in the theater. Let's subtract 6 from 184 to get our final answer:
184 - 6 = 178
Hope this was helpful! Let me know if you have any other questions abou this problem. :)
This is an algebraic equation. First we have a square the width is X
The length is L=3X-2. P (perimeter is 44)
Therefore P = 2L+2X
= 2(3x-2) + 2x
= 6x - 4 + 2x
= 8x - 4
44+4=8x
x=48/8
x=6
Ans: Width is 6 metres and length is 16 metres
