Given each of the following areas, what would be the radius of each circle? a. a = 530.66 m2 b. a = 907.46 sq. ft. c. a = 379.94 sq. mi. d. a = 1962.5 cm2
Answers: 1
. We will fill in each area and then solve for the radius. 
and 
. ∴
and r = 13. For b, 
and 
. 
, ∴ r = 17. For c, 
, and 
. ∴, 
and r = 11. For d, 
, and 
. ∴, 
so r = 25. And there you have it!
