Question

Radius = 3 ¼ydArea of a circle = ?help

Answer 1

Area of circle = 33.17 yd²

Step-by-step explanation:

First, we need to convert the number 3 ¼ yd into a decimal number, so:

`3(1)/(4)=3+(1)/(4)=3+0.25=3.25\text{ yd}`

Then, the area of a circle can be calculated using the following equation:

`\text{Area}=\pi\cdot r^2`

Where π is approximately 3.14 and r is the radius of the circle. So, if we replace π by 3.14 and r by 3.25 yd, we get:

`\begin{gathered} \text{Area}=3.14\cdot(3.25)^2 \\ \text{Area = 3.14 }\cdot\text{ (10.56)} \\ \text{Area = 33.17 yd}^2 \end{gathered}`

Therefore, the answer is 33.17 yd²
