You walk around a circle which has a diameter of 9 m, how far have you walked?
Snezhnost [94]

Answer:

C =28.26m

Step-by-step explanation:

We are walking around a circle, which means we are finding the perimeter.  The perimeter of a circle is called the circumference.

We find the circumference by

C = pi *d  where d is the diameter

C = 3.14 * 9

C =28.26m

Match the equation with the step needed to solve it.
saveliy_v [14]

To Match

To isolate -1 we need to subtract 2m from both sides

2m - 1 = 3m                    (SUBTRACT 2m)

To isolate 1 we need to subtract m from both sides

2m = 1 + m                 (SUBTRACT m)

To isolate m we need to add 1 from both sides

m - 1 = 2                       (ADD 1)

To isolate m we need to subtract 2 from both sides

2 + m = 3                   (SUBTRACT 2)

To isolate m we need to add 2 from both sides

-2 + m = 1                        (ADD 2)

To isolate m we need to subtract 1 from both sides

3 = 1 + m        (SUBTRACT 1)

The steps needed are written in bold.

If I drive 8.5 laps around a circular race track and during that drive I go 32 mi, what is the radius of the track? Round to two
Black_prince [1.1K]

Answer: The radius of the track = 0.64 mi

Step-by-step explanation:

Fr circular track , Total distance covered around it = (Number of laps) x (Circumference)  

As per given,

32 mi = 8 x (Circumference)

Circumference = \dfrac{32\ mi}{8}=4\ mi

Also, Circumference = 2\pi r , where r= radius so,

2\pi r=4\ mi\\\\\Rightarrow\ r=\dfrac{4}{2\pi}\\\\\Rightarrow\ r=\dfrac{2}{\pi}

Put \pi= 3.14

r=\dfrac{2}{3.14}\approx0.64\ mi

Hence, the radius of the track = 0.64 mi
