The heart shaped card is made by placing a square card and two semicircles together. What is the area of the card.

each side of the sqare is 8cm long.

I did a=TTr(squared)+lw

A=TT4squared+8(8)

A=TT16+64 A=80TT

A+251.3274123

A=251.3 cm(squared)

The total area of the card is

257.3cm(squared)

Can you please let me know if I did this correctly? Thanks

How did you get from

area=PI*16 +64 which is 114, to 251 then 257?

1st I added 16 plus 64=80. Then I multiplied 80 by TT and got 251.3

The last part should be 251.3 I messed up on the last number.

so is 251.3 correct?

Thank you for checking my work, I appreciate it.

I see what you did, but I thought TT was always done last, so I added and then multiplied TT.

Is there an order of operation for Pi?
