Hi there!
The formula for the area of a circle is A = pi x r^2. Using this formula, we can plug in the radius and solve for the area.
WORK:
A = pi x (5)^2
A = pi x 25
A = 25pi cm^2
ANSWER:
B - 25pi cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:
0.21
Step-by-step explanation:
Given that Jane is a better tennis player than Jack is. If the probability that Jane will beat Jack in any given game is 0.7,
Probability for Jane beating Jack is 0.7 and hence
Probability for Jack beating Jane is 0.3
We find that each game is independent of the other
If two games are played
Probability that they will each win one game if they play two games
= Prob that Jack wins one game * Prob that Jane wins one game
= 0.7*0.3
= 0.21
(Since if A and B are independent events P(AB) = P(A) *P(B)
