Answer:
Missing side = 6.7cm
Perimeter = 42.438cm
Step-by-step explanation:
The missing side will be the diameter of the semicircle
Missing side = 9.2cm - 2.5cm
Missing side = 6.7cm
Perimeter of the figure = Perimeter of rectangle + Circumference of the semi circle
Perimeter of rectangle = 2(L+W)
Perimeter of rectangle = 2(9.2 + 1.5)
Perimeter of rectangle= 2(10.7)
Perimeter of rectangle = 21.4cm
Get the circumference of the semicircle
Circumference of the semi circle= πd
Circumference of the semi circle = 3.14 * 6.7
Circumference of the semi circle = 21.038
Perimeter of the figure = 21.4cm + 21.038cm
Perimeter of the figure = 42.438cm
Answer:
term 1 = 5
term 2 = 8
term 3 = 11
term 4 = 14
term 5 = 17
term 6 = 20
term 7 = 23
every time the terms go up, 3 is added
I think C... I'm guessing cause my math is wrong
Answer:
P=p1+p2+p3+p4
P1=4*a=4*8=24
P2=a+b+c=6+10+8=24
P3=2*a+2*b=2*10+2*20=60=P4
P=24+24+60+60=160cm
