Answer:
Step-by-step explanation:
The volume of a cone of height h and circular base of radius r, is . In this case we have that .Then, we have that
multiplying by 3 on both sides and dividing by we have that
Suppose that we know the value of r, then we can find the value of h by solving h, that is
.
So, by choosing any positive value of r, we can find the value for h. Note that if r=6, then . This means that the amount of credit is infinite :)

Answer:
JL = 14
Step-by-step explanation:
N represents the center of the rhombus
Then
N is the midpoint of the diagonal (line segment) JL
Then
JL = 2 × NL
= 2 × 7
= 14
If the dimensions were all the same number ... the box was a cube ...
then each dimension would be (the cube root of 13,800) cm.
∛13,800 = 23.986... (rounded)
so the place to look is around 23 .
(22 x 23 x 24) = 12,144 <== too small; go up one integer
(23 x 24 x 25) = 13,800 <== Eureka !
The consecutive integers are 23, 24, and 25 .
Answer:
9 hours
Step-by-step explanation:
Let :
Landon hours = x
Ben hours = y
x + y = 14 - - (1)
60x + 56y = 820 - - - (2)
From (1)
y = 14 - x
60x + 56(14 - x) = 820
60x + 784 - 56x = 820
4x = 820 - 784
4x = 36
x = 36/4
x = 9
Landon drove for 9 hours
