The formula for lateral surface of a cylinder is:
SA = 2 *PI * r *h
Replace the letters with the given values:
400 = 2 * PI * r *40
Multiply the right side:
400 = r * 251.2
Divide both sides by 251.2:
r = 400 / 251.2
r = 1.59
The radius is 1.59 inches.
Answer:0.565
Step-by-step explanation:
Hat contain 100 coins out of which 99 is fair and one is double headed.
Probability of getting 7 heads is sum of Head through fair coin+heads through biased coin
Probability of getting a head through a fair coin=0.5
![P(7 heads)=0.99\times 0.5^7+0.01\times 1](https://tex.z-dn.net/?f=P%287%20heads%29%3D0.99%5Ctimes%200.5%5E7%2B0.01%5Ctimes%201)
![P(Double head |7 heads )=\frac{Probability\ of\ 7\ heads\ and\ double\ headed}{probability\ of\ 7\ heads}](https://tex.z-dn.net/?f=P%28Double%20head%20%7C7%20heads%20%29%3D%5Cfrac%7BProbability%5C%20of%5C%207%5C%20heads%5C%20and%5C%20double%5C%20headed%7D%7Bprobability%5C%20of%5C%207%5C%20heads%7D)

Step-by-step explanation:
Remark
This is an "in theory" type of question. She's going to actually need a little more.
Area 1
L = 15
W = 12 1/3
Area = L*W
Area = 15 * 12 1/3 I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark
Area = 15 * (12 + 1/3) Multiply both parts by 15
Area = 15*12 + 1/3 * 15
Area = 180 + 5
Area = 185 square inches.
Area 2.
This is a little harder because their are
2 fractions.
The easy way to do this is change to decimals
L = 10 1/3 = 10.33333333
W = 10 1/4 = 10.25
Area = 10.3333333 * 10.25
Area = <u> 105.92</u> Add
Total Area
The total area = 290.92
