OpenStudy (fuzzybird):

can you help with this one too? @Kdr1308 I don't understand it either.

OpenStudy (michele_laino):

area is given as area of rectangle + area of half circle

OpenStudy (michele_laino):

area of rectangle= \(12 \times 26=...\)

OpenStudy (fuzzybird):

=312

OpenStudy (michele_laino):

that's right!

OpenStudy (michele_laino):

area of half circle = \((3.14 \times 5 \times 5) /2=...\)

OpenStudy (fuzzybird):

so the total answer is 351.3 rounded

OpenStudy (michele_laino):

that's right!

OpenStudy (fuzzybird):
