Answer:
Solution given:
B=12.56cm²
P=12.56cm
H=6cm
Surface area of cylinder=P*H+2B=100.48cm²
Volume=B*H=12.56*6=75.36cm³
 
        
                    
             
        
        
        
No, it does not equal 0. Lets multiply it out and see what it actually equals.
15/25 * 25/15
15*25 / 25*15
375 / 375
Anything over itself is 1, so the final answer for the multiplication is 1.
        
             
        
        
        
The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
