Question

What is the approximate area of a circle with a diameter of 5 yards?

Answer 1

Given:

The diameter of the circle is 5 yards.

`\begin{gathered} r=(d)/(2) \\ r=(5)/(2)=2.5\text{ yards} \end{gathered}`

The area of the circle is,

`\begin{gathered} A=\pi* r^2 \\ A=\pi*(2.5)^2 \\ A=\pi*6.25 \\ A=(22)/(7)*6.25\ldots\ldots\text{ since }\pi=(22)/(7) \\ A=19.64\text{ square yards} \end{gathered}`

Answer: 19.64 square yards.
