If the diameter of circle O is 20 and CE = 4, then determine the length of AB. Show how you arrived at your answer.

Aneli [31]

Answer: Length of AB is 16 cm

Step-by-step explanation:

Given: Diameter of a circle is 20 cm and CE = 4 cm

Now as shown in figure AO, BO, CO are radii

$\text { Radius } =\dfrac{\text {Diameter}}{2} = \dfrac{20}{2} = 10 cm$

Therefore

AO=BO=CO= 10 cm

Now

$OE = CO- CE \Rightarrow OE= 10 -4 = 6 cm$

Now in Δ OEB

∠OEB =90°

Therefore by Pythagoras theorem : In a right angle triangle the square of hypotenuse is equal to the sum of square of other two sides.

So we have

$BO^2=BE^2+EO^2\\\\\Rightarrow 10^2= BE^2 +6^2\\\\\Rightarrow BE^2= 100-36\\\\\Rightarrow BE^2 = 64 \\\\\Rightarrow BE= 8 cm$

Now as we know perpendicular to the chord from the center of a circle bisect the chord.

Therefore

$AB= 2\times BE = 2\times 8=16 cm$

Hence , the length of AB is 16 cm .

A car travels 32 miles for each gallon of gas.How many gallons of gas does it need to travel 192 miles

gladu [14]

Hi there! :)

<u>Answer:</u>

The car needs <u>6 gallons</u> of gas to travel 192 miles.

Step-by-step explanation:

In order to answer your question, you'll need to use the cross product method:

32 miles → 1 gallon

192 miles → X gallons

<u>(1 × 192)</u> ÷ 32 = X gallons

<u>192 ÷ 32</u> = X gallons

<u>6</u> = X gallons

There you go! I really hope this helped, if there's anything just let me know! :)
