Remark.
Thank you for the clear diagram. You need to find AB somehow. When you do you can find the desired angle by using the inverse tan.
Step One
Find AB
AB = the radius of the cone
AB = 1/2 the diameter of the cone
AB = 1/2 * 4
AB = 2 inches.
Step two
Determine The Tangent of the desired angle
Tan(A) = opposite of adjacent
opposite side = h = 6 inches
Adjacent = AB = radius = 2 inches.
Tan(A) = 6/2 = 3
Step 3
Find the inverse Tan
A = inverse Tan(A)
A = inverse Tan(3)
A = 71.57 degrees <<<<< Answer.
There are other ways of finding the angle you want, but I think this is the quickest.
To find the unit price of each bag, divide each cost by the weight to find the cost of shrimp per pound.
For the 2.12 pound bag: 14.75 / 2.12 = $6.96 (rounded to the nearest cent)
For the 3.77 pound bag: 24.99 / 3.77 = $6.63 (rounded to the nearest cent)
You can tell that buying the 3.77 pound bag is better based on the unit price because of 6.63 < 6.96.
Answer:
254.34 in²
Step-by-step explanation:
Area of circle = 
d = 18 inches, so r = d/2 = 9 inches
Area = 3.14 * 9 * 9
= 254.34 in²
