From the above diagram, what is the area of the shaded portion?
The area of the shaded portion will be area of the square - area of the circle = L² - (πr²) (where L = 2r) = (20x20) - (π x x 10 x 10) = 400 - 314.16 = 85.84

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
