Answer: 2,048 in³
Step-by-step explanation:
Step 1: Find the radius
r=8
*Radius: 1/2 a circle*
Step 1: Plug the numbers into the formula
V= 4/3πr to the power 3
Even though pi is an irrational number, the question says to use 3 in its place.
V= 4/3(3)(8 to the power 3)
Step 3: Solve the equation
Method #1: Break it down using PEMDAS to solve manually
According to PEMDAS, exponents come first.
8³= 8x8x8= 512
Now, multiplication comes next, from left to right.
the first multiplication is 4/3x3= 4.
Finally, we have 4x512= 2,048 in³ (inches cubed).
That is the volume.
Method #2: Use a calculator
hope this helps :)) Brainiest would be appreciated
