Question

a circle has an area of 225 square inches. if the radius of the circle is multiples by 6, then what is the new area of the circle formed

Answer 1

Answer:

D:  8,100π in²

Step-by-step explanation:

The formula for area of a circle is

A = πr²

The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater.  So the area is

225π(36) = 8,100π
