Question

the radius of a circle is 3 inches. what is the area of the sector bounded by a 90° arc? answer in simplest form

Answer 1

1/4 x Pi x 3 ^2

Quarter x Pi x 3 squared

Answer 2

If the radius of the circle is 3 inches, then the area would be found by using the formula $\pi r^2$. You plug it in, and the formula would get us that the area is $9 \pi$ square inches. Since $\frac{360}{90}$ would equal 4, you would do $\frac{9}{4}$, which would equal $2 \frac{2}{5}$
