How do I solve questions 1,2 and 6?

Talja [164]

Answer:

Step-by-step explanation:

$1.\\\text{The length of semicircle:}\\\\l=\dfrac{1}{2}d\pi\\\\d-diameter\\\\d=2.2\\\\\text{substitute:}\\\\l=\dfrac{1}{2}(2.2)\pi=1.1\pi\approx(1.1)(3.14)=3.454\\\\\text{The perimeter of the figure:}\\\\P=2(3.8)+2.2+3.454=13.254$

$2.\\P=2(3.32)+2x=6.64+2x$

$6.\\\text{Look at the picture.}\\\\P=4(2)+2(1)=8+2=10$
