Question

Area of a circle how do you do this

Answer 1

Answer:

See below.

Step-by-step explanation:

The area of the circle is given by the formula:

$A=\pi r^2$

From the circle, we can see that the diameter is 14. Thus, the radius must be 14 divided by 2 or 7.

We're also using 3.14 for π. Substitute:

$A=(3.14)(7)^2$

Use a calculator:

$A\approx153.86$

And we're done!

Answer 2

Answer:

153.86cm2

Step-by-step explanation:

so the number in the middle of circle is the circumference, you just need to divided by to to find the radius, the you plug in the values.
