On a blueprint, a rectangular room 14 feet by 12 feet has a semicircular sitting area attached with a diameter of 12 feet. What is the total area of the room and the sitting area?

@elf,

I guess it's just like

14 ft base, and 12 ft height?

it doesn't matter since it's multiplication i guess

You need a calculator for that. Make the semicircle a circle, and work out the area of that circle with pi x radius^2

So use pi x 6^2

Afterwards, half your answer, and then add it to the area of the square.

Then you're done.

So just get 14 x 12 and add it to pi x 6^2

Wait, what is the radius... I could do radiusx2 to get diameter, then I can use an estimated guess and do diameterx3... I usually don't do 3.14 cause my teacher wants us to estimate it.

I got 224.56

It would be easier with a diagram, but I am pretty sure that is the answer

Ohh... It's a semicircle?? Hmm... Maybe radiusx2 (And that equals diameter) and then diameterx3 and then diameter/2 and that would get the area of the semicircle and then you add that with the 164 I got for the area of the room (I could be wrong with the area of the semicircle :\)

14 feet by 12 feet has a semicircular sitting area attached with a diameter of 12 feet.


14 x 12 = 168

area of a semicircle = half of pi x radius squared = 1/2(pi)(36) = 1/2(113.09) = 56.55

168 + 56.55 = 224.55

there you go
