X it is a straight line and goes through the origin
Answer: Its a function
Step-by-step explanation:
Answer:
Step-by-step explanation:
arccos(0) = 90 degrees
Cos is 0 when ever sin(x) =-1 this occurs at 270 degrees and when sin(x) = 1 at 90 degrees. However, the domain of arccos(x) is restricted from 0 to pi. So the value of arccos(0) is pi/2 or 90 degrees.
The diameter of the tank = 9 feet
So radius is = 
feet
Height of the tank = 25 feet
The top of the tank must be circular with same radius as 4.5 feet
So, to calculate the area of the tank and top, we will add the curved or lateral surface area of tank and area of circle
Curved or lateral Surface area of cylindrical area = 2*PI*r*h
= 
= 706.50 square feet
And area of the circular top = PI*r²
= 
= 63.585 square feet
So, total area that will be painted = 
= 770.085 square feet
Or rounding up to 2 decimal places = 770.09 square feet.
Answer:
10 inches.
Step-by-step explanation:
First we need to find what is the bigger dimension of the box, because the relay baton will occupy the box, and the larger dimension of the relay baton (that is, it's length) need to be less or equal than the larger dimension of the box.
The dimensions of the box are: 4 inches, 6 inches and 10 inches.
The larger dimension of the box is 10 inches. So, If we want the relay baton to fit in the box, the maximum length it can have is 10 inches.
