The curved dome has the area of half a sphere with radius 8 in. That is
... A = 2πr² = 2π(8 in)² = 128π in²
The lateral area of the cylinder is
... A = 2πrh = 2π(8 in)(7 in) = 112π in²
The area of the flat base is
... A = πr² = π(8 in)² = 64π in²
Then the total area of the figure is
... (128π + 112π + 64π) in² ≈ 304·3.14 in²
... = 954.56 in² . . . . matches the 2nd selection
Let 
denote the number of packages brought by customer 
. If, for instance, 
customers are in line, then the total number of packages is 
, and
since the number of packages brought by any customer is independent from the number of packages brought by any other.
a. 
is the probability that a total of 3 packages are waiting to get wrapped from among a total of 3 customers. This means each customer must have exactly one package. So
b. 
is the probability that a total of 11 packages are brought by 4 customers. The only way for there to be 11 packages is if 3 customers bring 3 packages and the last 1 brings 2. There are 
ways this can happen, so
Layla is creating a polygon with 4 equal sides in a circle.
This will be a regular polygon with 4 equal sides and 4 equal angles,
Layla is creating a square inside a circle.
I think the answer is 5, if you divide 7.5 by 1.45 you get 5.2 or 5.17 so approximately 5.
