Describe the change int he radius of a circle when the area is multiplied by 1/4.
Marianna [84]
I think the correct answer is C. Since a=πr², in order to get the area to become 1/4 of what it was previously, the radius needs to be cut in half to make the divide that side by 4.  a=π(r/2)²=πr²/4 and will therefore multiply the area by 1/4.
