Answer:

A= 78.4602

Step-by-step explanation:

To find the area of a circle, we would need the radius. We can find that from the circumference.

C=2πr

31.4=2πr

31.4/2π= r

r= 157/10π or 4.99747

Now we can use the radius to find the area of a circle.

A=πr^2

A=π(157/10π)^2

A= 78.4602

Problem #3

AfilCa [17]

Answer:

b = 115.4 feet

Step-by-step explanation:

b^2 = a^2 + c^2 - 2 (a)(b) x cos B

b^2 = 230^2 + 360^2 - 2(230)(360) x cos(38 degrees)

b^2 = 52,900 + 129,600 - 2(230)(360) x cos(38 degrees)

b^2 = 182,500 - 165,600 x cos(38 degrees)

b = $\sqrt{(16,900)(cos(38)) }$

b = 115.4 feet

i hope this helps!! :)
