Answer:
408.46cm^2
Step-by-step explanation:
Given data
Height= 13cm
Diameter= 10cm
Radius= D/2= 10/2= 5cm
The area of the curved surface will be = 2πr × h = 2πrh
substitute
Area of the curved surface = 2πrh= 2*3.142*5*13
Area of the curved surface = 2πrh= 408.46cm^2
Hence the area of the curve surface is 408.46cm^2
Answer: Yes, it is 125%
Step-by-step explanation:
Answer: 0.9730
Step-by-step explanation:
Let A be the event of the answer being correct and B be the event of the knew the answer.
Given:
If it is given that the answer is correct , then the probability that he guess the answer
By Bayes theorem , we have
Hence, the student correctly answers a question, the probability that the student really knew the correct answer is 0.9730.
The Answer Is:<span>4.222222</span>
4 2/9 = 4 + 2/9
= 4/1 + 2/9
= (4/1 * 9/9) + 2/9
= 36/9 + 2/9
= 38/9
= 38 ÷ 9 = 4.222222
Answer:
C
Step-by-step explanation:
the angle will always stay the same, it won't change
but if the dialation is 1/2, then that means that the sides will decrease in size compared to the original length,
(just divide by 2) on each side length to get the answer
