Answer:
C = 14pi units
C is approximately 43.96 units
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
C = 2*7*pi
C = 14 pi
If we approximate pi
C = 14*3.14
C =43.96 units
Answer:
![5\frac{1}{4}\text{ miles}](https://tex.z-dn.net/?f=5%5Cfrac%7B1%7D%7B4%7D%5Ctext%7B%20miles%7D)
Step-by-step explanation:
Given,
The number of miles she walks every day = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
∵ 1 week = 7 days,
⇒ 1 day =
week,
Thus,
The number of miles she walks
week= ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
⇒ The number of miles she walks in a week = ![\frac{3}{4}\times 7=\frac{21}{4}=5\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%5Ctimes%207%3D%5Cfrac%7B21%7D%7B4%7D%3D5%5Cfrac%7B1%7D%7B4%7D)
Equation: (1/2)(96) = 4x + 4
Solving for x:
0.5 * 96 = 4x + 4
48 = 4x + 4
44 = 4x
x = 11
Hope this helps!! :)
