Please answer this correctly

Answer 1

Answer:

  7.07

Step-by-step explanation:

The area of the whole circle is given by the formula ...

  A = πr^2

For the given values, the area of the circle is ...

  A = 3.14(3 in)^2 = 28.26 in^2

One-quarter of that area is ...

  (28.26 in^2)/4 = 7.065 in^2

The area of the quarter-circle is about 7.07 square inches.

Answer 2

Answer:

$= 7.065 {in}^{2}$

Step-by-step explanation:

$area = \frac{90}{360} \times \pi {r}^{2} \\ \frac{1}{4} \times 3.14 \times 3 \times 3 \\ = \frac{28.26}{4} \\ = 7.065 \: \: {in}^{2}$
