(adsbygoogle = window.adsbygoogle || []).push({}); If a circle has an area of t square units and radius r, then a circle with area 2t square units has a radius 2r

a) State whether or not the statement is true, Justify your answer.

b) If it is not true, rewrite the statement so that it is true.

50 = (4)(4)(pi)

100 = (5.6)(5.6)(pi)

5.6/2 does not equal 4, therefore the statement is false.

If a circle has an area of t square units and radius r, then a circle with area 4t square units has a radius of 2r.

50 = (4)(4)(pi)

200 = (8)(8)(pi)

Does this look ok?

I know, I ask a lot of questions but I want to make sure I understand this stuff
