Or
Pi x diameter = 3.14 * 20
2(3.14)(10)
If x = 2 and y = 3 then it can be solve as
3(2) + 3(3)
6 + 9

Answer:
16,000,000
Step-by-step explanation:
to start off your going to need to use PEMDAS (parenthesis exponents multiplication division addition subtraction)
so we are going to start IN the parenthesis the next step is doing the exponents so its going to look like this 1,000,000
rewrite the problem: 4(4×1,000,000)
use the next step in PEMDAS multiplication rewrite the problem:
4(4,000,000)
multiply: 16,000,000
