Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
 V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r 
 V = 4/3 π7^3
Evaluate the exponent 
 V = 4/3 π 343 
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343. 
v= (4/3*343)π
v=1372/3π 
If we want an exact answer, multiply 1372/3 and pi 
v=1436.75504 
So, the volume is 1436.75504 or 1372/3 π cm^3

Answer: width = 36 m
Step-by-step explanation:
Width = Volume / (height x length)
Width = 13500 / (25 x 15)
 = 13500/375
 = 36 m
 
        
             
        
        
        
Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60 
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!
