Calculate the surface area of a cylinder at waste bucket without a lid that measures 28 cm height and 18 cm in diameter give you
2 answers:
In this situation, the equation that you would be using is A = 2rh+2
r²
You have the Diameter: 18, and the height: 28
Since you have to use the radius in the equation, you would divide the diameter by 2 to get the radius, since the radius is half of the diameter.
The radius would be 9.
You will plug in 9 in R, and plug in 28 in H. Your equation would look like this:
2(9)(28)+2
(9)²
When you solve the equation, you would get 2092.3 cm. Then you would round it to the nearest whole.
The surface area of the cylinder is 2092 cm²

Answer:
Mary's risk premium is $0.9375
Step-by-step explanation:
Mary's utility function,
Mary's initial wealth = $100
The gamble has a 50% probability of raising her wealth to $115 and a 50% probability of lowering it to $77
Expected wealth of Mary,
= (0.5 * $115) + (0.5 * $77)
= 57.5 + 38.5
= $96
The expected value of Mary's wealth is $96
Calculate the expected utility (EU) of Mary:-
The expected utility of Mary is $9.75
Mary will be willing to pay an amount P as risk premium to avoid taking the risk, where
U(EW - P) is equal to Mary's expected utility from the risky gamble.
U(EW - P) = EU
U(94 - P) = 9.63
Square root (94 - P) = 9.63
If Mary's risk premium is P, the expected utility will be given by the formula:
Mary's risk premium is $0.9375
