3. If a circle has a radius of 7 feet, what is one-fourth of the circle's area? A A) 5.495 square feet
B) 9.61625 square feet
C) 38.465 square feet
D) 10.99 square feet

C 38.465 feet

Step-by-step explanation:

area of circle = pi(r2) or pi r (radius) squared

if the radius is 7, pi times (7) squared = 153.94

now 1/4 of 153.94 is around 38.4 so the answer is C
