Question

Help me plsss thx if u do✨✨

Answer 1

Since the value of r is given (r=2), just switch them => (8*2+1/4)^2 .
Then do the multiplication in the brackets: 8*2 and that is 16. Getting (16+1/4)^2.
Now just do the integer and fraction: ((64+1)/4)^2 => (65/4)^2 and then use a calculator to figure out what x squared is. In this case we get: 4225/16 or ≈ 264,1 .

Answer 2

Answer: 264.0625
8•2 is 16 + 1/4 and then 16 1/4 squared
