Answer: 4,188.79 u^3
Step-by-step explanation: Volume of a sphere is (4/3)pi•r^3
10^3 = 1000
(4/3) • pi • 1000 = 4,188.79 (rounded to 2 decimals)

Answer:
It is not an empty set
Step-by-step explanation:
A quadrilateral with 3 obtuse angles is possible.
A obtuse angle has a measure of more than 90 degrees and less than 180 degrees.
Let’s say three angles are measuring 91 degrees in a quadrilateral.
91 + 91 + 91 + x = 360
x = 87
The measure of the fourth angle is 87 degrees which is less than 360 degrees and is a positive integer, so it is possible.
 
        
                    
             
        
        
        
Answer:



Step-by-step explanation:
Given
Billy's Marble = x
Required
Determine a,b and c
a. Charlie's Marble
"5 more" means 5 + or + 5
Since Billy's Marble is represented with x, then Charlie's Marbles will be

b. Danny's Marbles
Having "8 fewer" means we have to subtract 8 from Billy's marble;
Since Billy's Marble is represented with x, then Danny's Marbles will be

c. Eric Marbles
Having "three times as " means we have to multiply Bill's marble by 3;
Since Billy's Marble is represented with x, then Danny's Marbles will be


 
        
             
        
        
        
It is the area of two triangle and one rectangle
area of a triangle is 1/*b*h
A=1/2*1.9*2.8=2.66 ft^2 multiply it by 2 as we have 2 triangle= 5.32 ft^2
Area of a rectangle=w*l=3.2*2.8 =8.96 ft^2
Add them =8.96+5.32=14.28ft^2
