A disk with a radius of cm costs US dollars(USD).
(a) Find an equation which links and . [3]
(b) Find, to the nearest USD, the cost of the disk that has a radius of
cm.
Answer:
(a) To find an equation that links the cost of the disk and its radius, we can use the given information that the cost is directly proportional to the cube of the radius. Let's denote the cost of the disk as C and the radius as r.
According to the given information, we can write:
C ∝ r^3
Since we are looking for an equation, we need to introduce a constant of proportionality. Let's call this constant k. Therefore, we can rewrite the equation as:
C = k * r^3
Now, we need to find the value of k. We are given that a disk with a radius of cm costs USD . Substituting these values into our equation, we get:
= k * (^3)
Simplifying further:
= k *
Now, we can solve for k by dividing both sides of the equation by :
k =
Therefore, our equation linking the cost of the disk (C) and its radius (r) is:
C = * r^3
(b) To find the cost of a disk with a radius of cm, we can substitute this value into our equation from part (a). Let's denote this cost as C1 and the radius as r1.
C1 = * (r1)^3
Substituting r1 = cm into the equation:
C1 = * (^3)
Calculating this expression will give us the cost of the disk to the nearest USD.
The answer to part (b) cannot be provided in this format as it requires specific numerical values for and r1. Please provide those values so that I can calculate and provide you with an accurate answer.

Answer:
<1 = 113
<2 = 67
<3 = 113
Step-by-step explanation:
m<2 = 67 (because of vertical angles)
<1 + 67 = 180
<1 = 113
<1 = <3 because of vertical angles
