Answer:
Perimeter of the semicircle is the formula r(π+2).
Radius r=14 cm
So, perimeter =14(π+2)... where π= 22/7
=2(22+14)=44+28=72 cm
So , the answer is
72 I guess
Step-by-step explanation:
Its False. addition and subtraction, Multiplication and division are inverse operations.
Hello!
1.
find circumferece
c=2pir
c=2*6*pi=12pi
intercept is 5.4
2pi radians=all
part/whole=part/whole
5.4/12pi=x/2pi
times both sides by 12pi
5.4=6x
divide both sides by 6
0.9=x
answer is 0.9 radians
2.
assuming 9pi/5 radians
find circumference
c=2pir
c=2*26.9*pi
c=53.8pi
arc/circumference=(9pi/5)/2pi
x/(53.8pi)=(9pi/5)/(2pi)
x/(53.8pi)=18/5
times both sides by 53.8pi
x=608.46266 m
about x=608.46 m
Hope this Helps! Have A Wonderful Day! :)
