The equation of a circle with center 
and radius 
is
In your case,
Plug these values into the generic formula and you'll get your equation.
Answer:
(2) 2,640 ft
Step-by-step explanation:
I'm going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.
The circumference formula is:
C = ⫪d
C stands for Circumference
d stands for diameter
I will use 22/7 instead of pi, so the formula looks more like this:
C = (22/7)(d)
The diameter is 840 feet, so we will substitute the variable d with 840:
C = (22/7)(840)
You can plug this part into the calculator, but by hand, it'll look something like this:
(22/7)*840 = (22*840)/7
18,480/7 = 2.640

Answer:
150
Step-by-step explanation:
The increase is by the factor 5/3, so the increased number is ...
90×(5/3) = 150
90 increased in the ratio 5 : 3 is 150.
Answer:
Math relationships
Step-by-step explanation:
A mathematical relation is, a relationship between sets of numbers or sets of elements. Often you can see relationships between variables by simply examining a mathematical equation. Many physical relationships in electrostatics, electrodynamics, thermodynamics, etc. are expressed by mathematical equations. hope this helps you :)
