<span>Since the h represents the number of hours spent working on the vehicle then the 75 represents the charge per hour for the work, leaving only the 0.08 which stands for the sales tax percentage which is 8% or 0.08 of the product of $75 times the number of hours worked on the car.</span>

A chord of a circle is 66cm long, it is 56 cm from the center of the circle. What is the radius of the circle?

ser-zykov [4K]

Answer:

radius = 65 cm

Step-by-step explanation:

(See image attached for better comprehension)

To find the value of the radius, we just need to draw a triangle, where one side is half of the chord (the distance from the chord to the center creates a point that divides the chord in two equal segments), other side is the distance from the chord to the center, and the hypotenusa will be the radius.

So, using Pythagoras' theorem, we have that:

r^2 = 56^2 + 33^2

r^2 = 4225

r = 65 cm
