Answer:
Length of the roof line is 
. And depth of the shed is 
Step-by-step explanation:
Given front wall is 11.5 feet tall, back wall is 20.2 feet. And roof rises at 30° angle from the front wall.
Let 
be the length of the roof line. And 
the depth of the shed.
We can see it is a right angle triangle with opposite 
(see the attachment)
Now,
Also,
So, Length of the roof line is . And depth of the shed is
Diameter d=16cm
d=r/2=8cm
Volume V(sphere)=4/3*pi*r^3
Therefore volume V=2145.52 cm^3
Hope this helps!

just figure out how many is made then multiple that by 15
Similar triangles have proportional corresponding sides and congruent corresponding angles.
For similar triangles we write
ΔGHI ~ ΔJKL
In these similarity expressions, the order of the vertices is meaningful. Here it tells us that G and J are corresponding vertices, as are H and K, as well as I and L. So ∠G≅∠J, ∠H≅∠K and ∠I≅∠L.
Answer: c
Answer: 9b
Step-by-step explanation: 8b+1b is the same thing as 8b+b whcih is basically 8+1 which is 9 but since it is attached to the letter b is becomes 9b.
