Question

A paper plate has a diameter of 9 inches. What measure is closest to the area of the plate?

Answer 1

The area of a plate with a diameter of 9 is 63.585

Explanation:

A = πr² use 3.14 as pi

r =
`(1)/(2)` d


`(1)/(2)` × 9 = 4.5

r = 4.5

A = 3.14 × 4.5²

A = 3.14 × 20.25

A = 63.585

Hope this helps!

Answer 2

63.62 inches squared

Explanation:

The formula for the area of a circle is πr^2

r (Radius) is half of the diameter

r = 9/2

r = 4.5in

π x 4.5^2=

π x 20.25 = 63.6172512352

to 2 dp: 63.62 inches squared.
