Formula for the area of a circle:
A = πr² (A = Area π(pi) r = radius)
You know:
r = 14 inches So substitute/plug it into the equation
[Radius is (half) of the diameter. The diameter is 28, so half of 28 = 14]
A = πr² Plug in 14 into "r" since r = 14
A = π(14)² Find 14² --> 14 x 14 = 196
A = 196π in² Your answer is the 4th option
Answer:
Solution: ,
Step-by-step explanation:
Given:
The rational equation to solve is given as:
Doing cross product, we get:
Now, for , the rational equation is equal to 0. So,
is a solution.
Also, is also a solution.
So, no extraneous solution.
