Answer:
A. 154 
Step-by-step explanation:
The formula for the area of a circle is 
First find the radius by dividing the diameter by 2, which is 7


≈154 
Answer:
98pi
Step-by-step explanation:
Area of circle: pi(r)^2
A1=pi(7)^2
A2=pi(7)^2
A2+A1=98pi
Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.



To isolate v, we can just multiply s to both sides and come up with the final equation below.

Thus, we have v = s(1 - F/f) with v as the subject of the formula.
Answer: v = s(1 - F/f)
