a chord of 12cm long of 8cm is away from the of the circle what is the lenght of the chord which is 6cm away from the centre
lana66690 [7]

Answer:

The length of the chord is 16 cm

Step-by-step explanation:

Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions

From the first part of the question, we can get the radius of the circle

The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle

Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

r^2 = 8^2 + 6^2

r^2= 64 + 36

r^2 = 100

r = 10 cm

Now, we want to get a chord length which is 6 cm away from the circle center

let the half-portion that forms the right triangle be c

Using Pythagoras’ theorem;

10^2 = 6^2 + c^2

c^2 = 100-36

c^2 = 64

c = 8

The full

length of the chord is 2 * 8 = 16 cm

Identify the corresponding word problem given the equation: x = 10.20 × 9
Inga [223]
10.20 x 9 = 91.8

( It's William and nine/eight friends, since they're dividing it among ALL people we count William in. )

A: William and nine friends <span>divided the bill evenly. If each person paid $10.20, what was the total bill? 
</span>
10.20 x 10 = 102

B: <span>At a restaurant, William and eight friends divided the bill evenly. If each person paid $10.20, what was the total bill? 

10.20 x 9 = 91.8

C: </span><span>At a restaurant, William and nine friends divided the bill evenly. If the total bill was $91.80, what did each person pay? 

91.80 x 10 = 918

D: </span><span>At a restaurant, William and eight friends divided the bill evenly. If the total bill was $91.80, what did each person pay? 

</span>91.80 x 9 = 826.2

So, your answer is B
