Question

A circle has an area 225π square inches. If the radius of the circle is multiplied by 6, then what is the area of the new circle formed?

Answer 1

Pi(r)^2 is area of a circle. Pi(r)^2=225(pi), solve for r. R=15. 15x6=90. New radius=90. Using area of circle formula, Pi(90)^2=8100 (pi)

Answer 2

8100π in. Squared
