Question

A DVD has a diameter of 34 centimeters. What is the area of the DVD? Round your answer to the nearest

hundredth. Use 3.14 for it.
The area of the DVD is about
cm

Answer 1

907.46cm

Explanation:

Area of Cirlce = πr^2

R= 17

R^2= 289

289 x 3.14 = 907.46

907.46cm

Answer 2

Area of the circle =
`907.46\;cm^2`

Explanation:

Diameter of the DVD =
`34\;cm`

`Radius=(34)/(2)=17\;cm`

Area of the circle=
`\pi * r^2`

As,

`\pi =(22)/(7)=3.14`

Area is:

`=3.14* 17* 17\\\\=3.14* 289\\\\=907.46\;cm^2`

Area of the circle is:
`907.46\;cm^2`
