Question

rose want to seed her circular garden with Kentucky Bluegrass grass seed, but she first needs to know how much area needs to be covered with seed. The garden is in a circular shape with a diameter of 9ft

Answer 1

Input data

The garden is in a circular shape with a diameter of 9ft

Procedure

The area of a circle is pi times the radius squared (A = π r²)

`A=\pi\cdot r^2`

We have information of the diameter of the circle we can calculate the radius.

d = diameter

r = radius

r = d/2

r = 9/2

r = 3 ft

`\begin{gathered} A=\pi\cdot(3)^2 \\ A=\pi\cdot9 \\ A=3.14\cdot9 \\ A=28.26 \end{gathered}`

The area would be equal to 28.26 ft^2
