2. The diameter is 24 cm. Find the length of CD to the nearest tenth

(Reminder: the DIAMETER is given.)

Length of arc = 12.6 cm

Step-by-step explanation:

CD is an arc. We would apply the formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Diameter = 24 cm

Radius, r = diameter/2 = 24/2

Radius = 12 cm

θ = 60 degrees

Therefore,

Length of arc = 60/360 × 2 × 3.14 × 12

Length of arc = 12.6 cm rounded up to the nearest tenth.

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
