Answer:
A: 20
Step-by-step explanation:
4+4+4+4+4= 20
Use the following formulas.
C=2pir r= radius, pi=3.14
A=pir^2 r = radius pi=3.14
R=1/2d d = diameter
The diameter is 12 feet so the radius is 6, plug into the equations...
C = 2pi(6)
A = Pi6^2... Plug these into your calculator to find the answers. Or if you are asked to leave the answers in terms of pi you should get A = 12pi and C =36pi
Hope that helps!
For the answer to the question above asking to u<span>se a system of inequalities to model the scenario above. Let x represent babysitting hours and y represent tutoring hours.
</span>I would start with a simple equation 6x+10y is more than or equal to 75
Right away looking at it I would do y=7 and x=1 then the total can become $76
