Question

Step by step answer Find the area of a circle with a radius of 3 yd. ( = 3.14)

Answer 1

Given: The radiusof a circle as below

$\begin{gathered} radius(r)=3yd \\ \pi=3.14 \end{gathered}$

To Determine: The area of the given circle

Solution

Step: Write the formula for finding the area of a circle

The area of a circle can be calculated using the formula below

$\begin{gathered} Area(circle)=\pi r^2 \\ Where \\ radius \end{gathered}$

Step 2: Substitute the given value of radius into the formula

$\begin{gathered} Area=\pi r^2 \\ Area=3.14\times(3yd)^2 \\ Area=3.14\times9yd^2 \\ Area=28.26yd^2 \end{gathered}$

Hence, the area of the given circle is 28.26yd²
