Answer:
Option B is correct
Step-by-step explanation:
Given: 
To find: interval on which
must fall
Solution:


Subtract (ii) from (i)

So,
must fall in interval 
Therefore, option B is correct.
<u>Given</u>:
The arc length for the given sector is 7π
The central angle for the given sector is θ
The radius of the circle is r.
We need to determine the formula for r in terms of θ
<u>Formula for r:</u>
The formula for r in terms of θ can be determined using the arc length formula,

Substituting the values, we have;

Dividing both sides by θ, we get;

Thus, the formula for r in terms of θ is

Answer:
Part a) 119 cups
Part b) 30 cups
Step-by-step explanation:
Part a)
step 1
Find the volume of the conical cup with a diameter of 4 in. and a height of 8 in
The volume of the cone (cup) is equal to

we have
----> the radius is half the diameter

assume

substitute

step 2
Find out how many cups of water must Carissa scoop out of the sink
Divide the volume of the sink by the volume of the cup
so

Part b)
step 1
Find the volume of the conical cup with a diameter of 8 in. and a height of 8 in
The volume of the cone (cup) is equal to

we have
----> the radius is half the diameter

assume

substitute

step 2
Find out how many cups of water must Carissa scoop out of the sink
Divide the volume of the sink by the volume of the cup
so
