A road bike has a wheel diameter of 622 mm. What is the circumference of the wheel? Use 3.14 for pi

Ghella [55]

Answer:

Circumference ≅ 195 mm

Step-by-step explanation:

The circumference of a circle is equal to: $2*\pi *radius$

Since $Diameter = 2*radius$ we can replace that in the circumference equation giving us:

$Circumference = \pi *Diameter$

We know Diameter = 622 mm and pi = 3.14 so:

$Circumference = \pi *Diameter = 3.14 * 622 mm = 195.308 mm$

Answer: $\bold{a)\quad E=\dfrac{1}{5}s}$

b) 75

c) $24

<u>Step-by-step explanation:</u>

the difference in the y-values (electricity) divided by the difference in the x-values (students) is the rate of change. $\dfrac{10}{50}=\large\boxed{\dfrac{1}{5}}$

Electricity = rate of change × students ⇒ $E=\dfrac{1}{5}s$

b) Find s when E = 15

$15=\dfrac{1}{5}s\\\\\\(5)15=(5)\dfrac{1}{5}s\\\\\\\large\boxed{75 = s}$

c) Find E when s = 120

$E=\dfrac{1}{5}\times 120\\\\\\E=\dfrac{120}{5}\\\\\\\large\boxed{E=24}$
