A rectangular sheet of metal measuring . 50 cm by 30 cm has a semicircle of radius 15 cm cut from each short side as shown . Find the perimeter of the shape that is left .

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

6e14 is the answer.

the correct option is b

step-by-step explanation:

m∠a is 90°

m∠b is 40°
