Question

Radii of the two circles are 8 cm. and 3 cm. (diagram is not to the scale). Use = 3.14

Answer 1

I'm not sure if this is what you were asking for but if it's not just tell me and I'll change it. :)

Explanation:

Circle one:

Area =
`\pi r^(2)`

`=(3.14)(8^2)=`
`(3.14)(64)=200.96`

Circumference =
`2\pi r`

`= 2(3.14)(8) = (3.14)(16) = 50.24`

Circle two:

Area =
`\pi r^(2)`

`=(3.14)(3^2)=`
`(3.14)(9)=28.26`

Circumference =
`2\pi r`

`= 2(3.14)(3) = (3.14)(6) = 18.84`
