Question

- A six-foot diameter circular table

top has an area of about how many
square feet? (Use 3.14 for a.)
.

Answer 1

28.26

Explanation:

area of a circle is (pi)(r)^2

radius is half of the diameter

6/2=3

3 feet is the radius

a= 3.14 (3)^2

=3.14 x 9

= 28.26 feet

Answer 2

Hi!

-------------------------------------------------------------------------------------------------------------

Area of a circle =
`\pi r^2`

Radius (r) =
`(diameter)/(2)`

-------------------------------------------------------------------------------------------------------------

In this problem:

`r=`
`(6)/(2)`

`r=`
`3`

`3.14 (3)^2`

`3.14(9)`

`28.26`
