    to find the circumference of the circle, divide it by two since it is a half circle then add the perimeter of the rectangle like @triciaal is showing you

    @YoungTrilogyFT3 correct explanation minor adjustment only 3 sides of the rectangle and add the semicircle

    then you only have to calculate perimeter of semicircle then add side length of that rectangle.

    And you know that \(C = 2\pi r\) So half circumference would be \(\dfrac{C}{2} = \pi r\)

    9+8+9= 26 so then im guessing to do \[12.56 \div 26\]

    You have 2 apples and you have other three apple. To find total apple, you don't do division, right? You would use addition.
