Answer:
36.53 cm²
Step-by-step explanation:
Picture this repeated four times to make a circle. The circle would have a radius of 8. r² would give us 201.06. One quarter of that would be 50.265.
The area of the square is length times width, or 8X8=64.
64-50.265=13.735. That would be ONE of the non shaded sections of the square. If you take that away twice, the leftover part would be the shaded area.
64-13.735-13.735=36.53 cm²
Answer: Our required probability is 0.18.
Step-by-step explanation:
Since we have given that
Probability that husband is on the internet = 10% = 0.10
Probability that husband is not on the internet = 1-0.10 = 0.9
Probability that wife is on internet given that husband is on internet = 40% = 0.40
Probability that wife is on internet given that husband is not on internet = 20% = 0.20
Probability that wife is on internet is given by
So, Probability that the husband is also on internet given that wife is on internet is given by
Hence, our required probability is 0.18.
