Answer:
Step-by-step explanation: Since area is found by radius, we must decide what should have been used. Take half of 6 and you have 3.
Now squaring 3, using the formula gives us 9. Hoshi squared 6 giving him 36. This is 4 times greater. That's because his value was 2 times greater and when we squared it that made it 2 more times greater, or 4 times greater.
Pi cancels itself and does not affect the outcome.
