Question

Find the area of this circle. Use 3 for a.=A = ar2A = T?[?]= T16 inHint: First plug the value of theradius into the formula for r.Since the diameter is 16, theradius is 16 divided by 2.

Answer 1

Looking at the image, we can see that the diameter of the circle is 16 inches.

Since the radius measures half the diameter, so the radius of this circle is equal to 8 inches.

So the missing value in the area formula is 8.

Then, calculating the area, we have:

`\begin{gathered} A=\pi\cdot8^2 \\ A=3\cdot64 \\ A=192\text{ in}^2 \end{gathered}`

The circle area is equal to 192 in².

Since the question first asks only for the missing value in the formula, so the
