Surely you mean divide by pie then square root the result?

lol

This will be someone who got a GCSE when they were giving them out with a 10p mix up from the tuck shop.

The answer is 3.8197 but as you only said the area is 144 not 144sq (units) your answer would be marked incorrect :)

Though the formula was always taught as πr2 the true formula is ((r2)xπ)
