How to do this question
blsea [12.9K]
This is a 3 step problem. First you ignore the hole in the middle and find the volume anyways. Then you find the volume of the empty middle part. Then you can find the volume of the actual shape by subtracting them. 
area of a circle is= pi r^2
Volume with hole: 5*5*pi*8=200pi
Volume of hole= 1.5*1.5*pi*8= 18pi
Volume of doughnut = 200pi-18pi=182pi=571.769863u^3

r is the radius which is half of the diameter. 
pi is a big number but you can use 3.14
the formula for finding the volume is area of base times height. That's why i multiplied it by 8.]

I hope this helps

What is the area of the figure?
Minchanka [31]

9514 1404 393

Answer:

  (C)  64.26 m²

Step-by-step explanation:

You know the area is almost, but not quite, the area of two squares that are 6 m on a side. The area of one of those squares is (6 m)² = 36 m². The area of two of them is 2×36 m² = 72 m².

Since the area is larger than 36 m² and smaller than 72 m², there is only one answer choice that makes any sense:

  64.26 m²

__

<em>Additional comment</em>

That value is obtained using 3.14 for pi.
