Question

Please it looks like a lot but this is due in 3 hours and I spent the entire night doing work and I just want to sleep a little before my class starts

Answer 1

It is given that the diameter of largest circle is 8 and diameter of circle is 4.

The radius of largest circle is 4.

The area of the largest circle is given by

`A_1=\pir^2`

where r = 4.

Hence the area is

`16\pi`

The area of the samllest circle is given by

`a=\pi(2)^2`

Hence the area of smallest circle is

`8\pi`

The ratio of largest to smallest circle is given by

`\text{ratio}=(16\pi)/(8\pi)=2\colon1`

Hence the ratio is 2:1
