Answer:
24 cm
Step-by-step explanation:
The altitude from the centre to the chord is 5 cm and bisects the chord.
The radius of the circle is 26 cm ÷ 2 = 13 cm
There is a right triangle formed with legs 5 and x ( x is half the chord )
The hypotenuse is the radius, then using Pythagoras' identity
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = 
= 12
Then
length of chord = 2x = 2 × 12 = 24 cm
Answer:
$8.75
Step-by-step explanation:
Given data
Bill= $25
Coupon Discount=15%
Tip= 20%
Let us first find 15% of the $25
=15/100*25
=0.15*25
=$3.75
Let us first find 20% of the $25
=20/100*25
=0.20*25
=$5
Hence the coupon and the tip combined is
=3.75+5
=$8.75

Answer:
s = 35pi units
We can either leave it with pi in the answer or approximate
s= 109.9557429 units
Step-by-step explanation:
Arc length is found by
s = r * theta where r is the radius and theta is given in radians
Changing the angle from 150 degrees to radians by multiplying by pi/180
150 *pi/180 = 5/6 pi
Now we can use the formula
s = 42 * 5/6 pi
s = 35pi
We can either leave it with pi in the answer or approximate
s= 109.9557429 units
