Answer:
Step-by-step explanation:
radius=diameter/2
=8/2
=4 m
volume of a cylinder =πr^2h
=3.14*(4)^2*13
=40.82*16
=653.12 m^3
Answer:
x(x - 4) = 12
x2 - 4x = 12
x2 - 4x - 12 = 0
(x - 6)(x + 2) = 0
x - 6 = 0
x = 6
If the length is 6, the width must be 2.
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
It is not because 20 is not a perfect square.
Let x be the number of boys, then,
(3*x*18+x*y)/(3x+x)=17
(54+y)/4=17
y=14 points each boy.
