(-9k+8k)*-1
9k-8k=1k
1k*-1=-1k
your answer is -1k
Answer:
50.24 in.
Step-by-step explanation:
Radius of Big circle ( R ) = 2 + 3 = 5 in.
Radius of Small circle ( r ) = 2 in.
Area ( Shaded region )
= Area ( Big circle - Small circle )
= πR² - πr²
= π ( R² - r² )
= 3.14 ( 5² - 3² )
= 3.14 ( 25 - 9 )
= 3.14 × 16
= 50.24 in.
Answer:
A possible solution is that radius of cone B is 2 units and height is 36 units
Step-by-step explanation:
The volume of a cone is given by

where
r is the radius
h is the height
Here we are told that both cones A and B have the same volume, which is:

And
(2)
We also know that cone A has radius 6 units:

and height 4 units:

For cone B, from eq.(2), we get

One possible solution for this equation is

In fact in this case, we get:

Therefore a possible solution is that radius of cone B is 2 units and height is 36 units, and we know that in this case Cone B has the same volume as cone A because it is told by the problem.
Step-by-step explanation:
Let F = The number of $5 bills and T = the number of $10 bills. She has 15 bills total, so:
F+T = 15
T = 15-F
She has $120 total:
$120 = ($5)*F + ($10)*T
$120 = $5*F + ($10)*(15-F) [Substitute 15-F in place of T]
120 = 5F + 150 - 10F
-30 = -5F
6 = F
Check:
T= 15-F = 15=6 = 9
$120 = ($5)*6 + ($10)*9
$120 = $30 + $90
$120 = $120
