Your dog, Cujo, has a water bowl, shown below, that is in the same shape of a right circular cylinder with a diameter of 8 inches. The bowl is filled with water to a uniform depth of 4 inches. What is the volume of the water in the water bowl, in cubic inches?
A. 12
B. 16
C. 32
D. 64
E. 256

The answer to your question is the letter D. 64π

Step-by-step explanation:

Data

diameter = 8 in

depth = 4 in

Volume = ?

Formula

Volume of a cylinder = πr²h

Process

1.- Calculate the radius

   radius = 8 /2

   radius = 4 in

2.- Calculate the volume

- Substitution

  Volume = π(4)²(4)

- Simplification and result

  Volume =  π(16)(4)

  Volume = 64π

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
