8. For circle A, the circumference is 31.4 ft. What is the area? Use 3.14 for pi

telo118 [61]

Answer:

$\huge\boxed{\sf A = 78.5\ ft\²}$

Step-by-step explanation:

Circumference = C = 31.4 ft

We know that,

Where, r is the radius

31.4 = 2(3.14)r

31.4 = 6.28(r)

Divide 6.28 to both sides

31.4/6.28 = r

5 ft. = r

Now,

<h3><u>Finding area:</u></h3>

A = πr²

A = (3.14)(5)²

A = (3.14)(25)

$\rule[225]{225}{2}$
