Answer:
A. 2827 square cm
Step-by-step explanation:
Diameter of circle = 60 cm
Therefore, radius = 60/2 = 30 cm
Answer:
None of the above
Step-by-step explanation:
According to the divergence test, if the limit of a sequence as n approaches infinity does not equal 0, then the series diverges. (Notice that if the limit does equal 0, the series doesn't necessarily converge).
According to the geometric series test, a geometric series converges if -1 < r < 1, and diverges otherwise.
The first series is a geometric series with r = -5/3. So it diverges.
The second series is also a geometric series:
3ⁿ⁻¹ / 2ⁿ = ⅓ (3ⁿ / 2ⁿ) = ⅓ (3/2)ⁿ
r = 3/2, so it diverges.
For the third series, the limit as n approaches infinity equals 1. This fails the divergence test, so this series also diverges.
For the fourth series, the limit as n approaches infinity equals 1. This fails the divergence test, so this series also diverges.

Answer:
<h2>D. (-1, -3)</h2>
Step-by-step explanation:
A, FE as a chord is a straight line that goes from one end of the circle to another end. This means both ends of the line should touch the circumference. In FE, only one end of the line is touching the circumference. The other isn't. There FE isn't a chord for circle F
