Describe the change int he radius of a circle when the area is multiplied by 1/4.

Mathematics

Marianna [84]3 years ago

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.

ziro4ka [17]
The answer is 56.

I know this because...
<span>-6 + {14 + 2 [60 − 9(1 + 3)]}
-6 + </span>{14 + 2[60 − 9(4)]}
-6 + {14 + 2[60 − 36]}
-6 + {14 + 2[24]}
-6 + {14 + 48}
-6 + {62}
-6 + 62 = 56
