The circumference of Tyler's bike tire is 72 inches. What is the diameter of the tire?

pantera1 [17]

Answer:

The diameter is 22.92 inches

Step-by-step explanation:

Hello, I can help you with this question

in this case we know the circumference of a circle, and we need to find out the diameter.

let's remember

the radius of a circle can be defined as

$radius=\frac{diameter}{2}\\ or\\diameter=2* radius( equation\ 1)\\$

also

$circumference=2*\pi *radius(equation2)\\$

Step1

replace the value of the circumference of tyler's bike in equation 2 and isolate radius to find radius

$72 inches=2*\pi *radius\\\\radius=\frac{72}{2*\pi } \radius =11.46\ inches$

Step 2

now, replace the value of radius into equation 1 to find diameter

radius=11.46 in

$diameter=2* radius( equation\ 1)\\\\diameter=2*11.46\\diameter=22.92$

so, the diameter is 22.92 inches

I really hope it helps, have a great day.

katovenus [111]

Answer:

55/43

Step-by-step explanation:

(x/y) = 7/3, (x^2/y^2)=49/9, multiply by 3 above and multiply 2 below, 3x^2/2y^2=147/18. Next apply C&D and you will get (3x^2+2y^2)/(3x^2-2y^2)=(147+18)/(147-18)=165/129=55/43

QUESTION 2 21 Write THREE equivalent actions for the following traction 25/50

MrMuchimi

The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .

<h3>What are equivalent fractions</h3>

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, $\frac{2}{4}$ and $\frac{3}6}$ are equivalent fractions, because they both are equal to the $\frac{1}{2}$ . A fraction is a part of a whole. Equivalent fractions represent the same portion of the whole.

Given that:

$\frac{25/25=1}{50/25=2}$

$=\frac{1}{2}$

$\frac{25/5=5}{50/5=10}$

$=\frac{5}{10}$

$\frac{25*2=50}{50*2=100}$

$=\frac{50}{100}$

Therefore, The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .
