Accepted Solution

A:

PART ;

......Circle A.................

Circumference - 2 pi r

25.12 = 2pi(4)

25.12 = 8i

Divide both sides by 8!!

3.14=pi

...Circle B.....................

Circumference = 2 pi r

9.42 = 2pi(3/2)

9.42 = 3pi

Divide both sides by 3!!!

3.14 = pi

PART B

.............Circle A...............

A=pi r ^2

50.24 = pi(4)^2

50.24=16pi

Divide both sides by 16!!!

3.14=pi

.............Circle B.............

A=pi r^2

7.065=pi(3/2)^2

7.065= 9pi/4

Divide both sides by 9/4!!!

3.14=pi

PART C

They used exactly 3.14 for the value of pi in CIRCLE A and B to get the circumference and the area :D

I hope this makes sense!!!

When I wrote 'pi', it was supposed to be the symbol for pi.
