Answer:
Area of red band is 
Step-by-step explanation:
We know that area of square = 
Please refer to the attached figure, we have to calculate the area of red band.
Required area = Area of square <em>ABCD </em>- Area of <em>purple square
</em>
Side of purple square = 
So, area of purple square = 
<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.
So, width of red band towards both the end is 5 inches.
Required area = 
Using formula 
Hence, Area of red band is
Answer:
2 hours and 45 minutes
Step-by-step explanation:
Well, the function is an equation used to find slope, called slope-intercept form: y=mx+b f(s) being y, 8 being the slope or m, s being the x coordinate, and 15 being b or the y-intercept.

Answer:
89.80 cm cubed
Step-by-step explanation:
A hemisphere is essentially just half of a sphere. We want to find its volume.
The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.
Here, the radius is 3.5, so plug this in:
V = (2/3)π * r³
V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed
