Question

I need help ASAP you have to find the area of the circle

Answer 1

Answer:

A = \pi r^2

Step-by-step explanation:

to make this simpler i can solve this for you.

To insert the number into the equation you go like this,

A=(pi)r^2

The diameter is that whole line in the circle which is 16 and the r or radius is half the diameter so you would do 16/2, which equals 8. then you insert that into the equation.

A=(pi)8^2

8 to the 2nd power is 64

And im going to round pi to 3.14

so no the equation is

A=3.14*64

The area is 200.96 mi ^2 or rounded 201 mi^2

Answer 2

Answer:

Step-by-step explanation:

A=πr^2 is the equation for the area of a circle. You are given the diameter, and the radius is just one half the diameter.

A = π8^2

A = 64π or 201.06
