Answer:
Speed of bug will be 5.2822 cm /sec
Explanation:
We have given radius of the circular planter = 11.7 cm
We know that circumference [tex]C=2\pi r=2\times 3.14\times 11.7=73.476m[/tex]
It is given that bug completes on lap in 13.91 sec
So time t = 13.91 sec
We have to find the speed that is how fast it was traveling
So speed [tex]v=\frac{distance}{time}=\frac{73.476}{13.91}=5.2822cm/sec[/tex]
So speed of bug will be 5.2822 cm /sec
Answer:
8.5.28 492 cm/s
Explanation:
We are given that a bug completes one lap along edge of circular planter.
Radius of circular planter=11.7 cm
Time taken by bug=13.91 s
We have to find speed of traveling of bug
We know that speed =[tex]\frac{distance}{time}[/tex]
Distance traveled by bug=[tex]2\pi r[/tex]
[tex]\pi=3.14[/tex]
Distance traveled by bug=[tex]2\times 3.14\times 11.7[/tex]
Speed of bug=[tex]\frac{2\cdot 3.14\cdot 11.7}{13.91}=5.2822 cm/s[/tex]
Hence, option 8 is true.
Answer: 8.5.28 492 cm/s
