Answer:
The radius of the circle is approximately 14.42cm
Step-by-step explanation:
If the length of the chord is 16cm and it is 12cm from the center of the circle.
it means it forms 2 right angles while dividing the center of the chord, to the center of the circle, and at right angle. Length of the adjacent then become 16/2 = 8cm
To calculate the radius which forms hypothenus of the right angle triangle, we use Pytagoras Theorem
Say = + , where r is the radius of the circle
= 144 + 64
= 208
r =
r = 14.4222
r ≈ 14.42
Answer:
He should charge 15.75
Step-by-step explanation:
Markup = original price * markup rate
Markup = 9*75%
= 6.75
The new price is the original price plus the markup
New price = original price + markup
New price = 9+6.75
= 15.75
He should charge 15.75
