6π square inches


B.


12π square inches


C.

Answer 1

what do you think

Answer 2

\(A = \pi r^2\)

The radius is half the diameter.

12 / 2 = ?

Answer 3

6

Answer 4

12/2 = 6

Answer 5

Yes, that is the radius, plug it in the formula:

\(A = \pi(6^2)\)

Simplify \(6^2\)

Answer 6

A≈113.1in² i thinkz

Answer 7

so Simplify 36

Answer 8

yes

Answer 9

Yes, so we have \(36\pi\).

Answer 10

That's our answer \(\Huge\ddot\smile\)
