A circular plot of land has a diameter of 16 yards. What is the area of theland? Use 3.14 for it.O A. 803.84 yd2O B. 50.24 yd2O

Amiraneli [1.4K]

The area of the circle can be calculated with the following formula

$A=\pi\cdot r^2$

First let's find the radius

$\begin{gathered} r=\frac{16}{2}\text{yds} \\ r=8\text{yds} \end{gathered}$ $\begin{gathered} A=\pi\cdot8^2 \\ A=3.14\cdot64 \\ A=200.96\text{ yd2} \end{gathered}$

The answer would be 200.96 square yards
