Answer:
The least common denominator is (b-8)(b+8)(b-1)
Step-by-step explanation:
We are given expression as
Firstly, we will factor both denominators
so, we can plug it back
First term denominator is
(b-8)(b+8)
Second term denominator is
(b+8)(b-1)
So,
Least common denominator will be
(b-8)(b+8)(b-1)
So, we get
Answer:
The area of the circle is 28.26.
Step-by-step explanation:
πr =9.42
Using that, we can find the radius, which will help us find the area of the circle.
9.42/π = 3 (I used 3.14 for π)
The formula for area of a circle is:
πr^2
Plug our values in.
π(3^2)
9π
28.26
The area of the circle is 28.26.
To sum, Min would need to first figure out the radius of the circle, and then use the radius to find the area of the circle. She can figure out the radius by dividing 9.42 by π, and find the area with the formula πr^2.
I think it’s .2 I could be wrong but just use a calculator.
Answer:
The chord is 10cm from the center of the circle
Step-by-step explanation:
Here, we want to find the distance of the chord from the center of the circle
A line from the center to the chord will
divide the chord into two parts
each will have a measure of 48/2 = 24 cm
So now we have a right/angled triangle with hypotenuse of 26
To find the height, we use Pythagoras’ theorem which states that the sum of the squares of the other sides equal the square of hypotenuse
h ^2 + 24^2 = 26^2
h^2 = (26-24)(26+24)
h^2 = 100
h = square root of 100, which is 10
