How do I do this? I need it in perimeter to 2 decimal places. Thank you!

Step-by-step explanation:

do this in two parts.  one, the rectangle,  two, the circle

the rectangle , you only have 3 sides to the rectangle.

2 * 25 = 50

1* 30 = 30

total perimeter of the rectangle = 80 cm

the circle, find the total of the circle, then since there is only half and circle,  multiply that by  1/2 or divide by 2, same thing.

perimeter of a circle is the circumference

circumference of a circle is  2r   or   diameter   ,  same thing

30 = 94.24777961 cm ( the whole circle )

1/2*94.24777961 =47.1238898 cm

add the two parts

  80 + 47.1238898 = 127.1238898 cm

127.12  cm  ( rounded to two decimal places )

not sure but it may be b, as i said i'm not sure.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
