An earthquake was felt throughout a circular region with a radius of 540 km; find the total area of the region affected.

Answer 1

The total area of the region affected is 9,539,600 km^2.

Area = πr^2

Area = π(540 km)^2

Area = 9,539,600 km^2

Answer 2

Yes

Answer 3

Again, the bot can't seem to be able to do basic arithmetic

Area = π (540)^2 km^2
= 916,088.4 km^2
