Answer:
A = πr^2
Step-by-step explanation:
Area = π x r (radius of the circle) squared
I think the answer is 64.5
For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Answer:
133 degrees
Step-by-step explanation:
if FBE is 47 degrees and is identical to angle CBD, then we can consider
EBD as 180 degrees first and subtract 47 degrees, which is 133 degrees, that is how I got my answer.
hope it helped in any way.
