Question

The diameter of a circle is 3 feet. What is the area?Give the exact answer in simplest form. ____ square feet.

Answer 1

7.1 square feet

Step-by-step explanation:

The area of a circle can be found using the below formula;

`A=\pi* r^2`

where pi = 3.14

r = radius of the circle = d/2 = 3/2ft

Let's go ahead and substitute the above values into our formula and solve for A,

`\begin{gathered} A=3.14*((3)/(2)) \\ A=3.14*(9)/(4) \\ A=7.1square\text{ ft} \end{gathered}`
