Answer 5

do a little calculation..

find the area and circumference is 1 unit...

then double the radius r = 2 then calculate the circumference and area...compare the results.

Answer 6

?

Answer 7

use the formulae for

1. circumference \[C = 2 \pi r\]

2, Area

\[A = \pi r^2\]

firstly with a radius of r = 1 unit find the area and circumference of the circle

then use a radius of r = 2 units to find the area and circumference of the circle

then compare you answers fo r = 1 and r = 2

the information for the comparison of the circumference will be different to the information for the area.

hope it helps
