Question

If a circle has a radius of 3 what is the area

Answer 1

Answer:

Area of circle = πr×r

= 22/7×9

= 28.28 square cm

= 28.3 square cm (Approximately)

Answer 2

Answer:

Area Of A Circle = π × r²

Given :- r = 3

=> Area Of Circle = (3.14) × (3)² -or- (22/7) × (3)²

=> Area = 28.26 squnits (if π = 3.14)

=> Area = 28.28 squnits (if π = 22/7)
