Answer:
2
Step-by-step explanation:
The products of chord lengths are the same for the intersecting chords:
AQ×BQ = CQ×DQ
6×12 = CQ×(38 -CQ)
This gives a quadratic in CQ:
CQ² -38CQ +72 = 0 . . . . . write in standard form
(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic
CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero
The minimum length of CQ is 2 units. (DQ will be 36.)
For questions like this just multiply the prices by how many they're buying and add all the numbers up and subtract by how much they have to begin with.
Example:
$34.99×2=$69.98
$16.50×3=$49.50
$3.75×4=$15
$69.98+$49.50+$15=$134.48
$134.48-$125=$9.48
The volume of a cone is calculated through the equation,
V = (πD²/4)(H)/3
where V is volume,
D is diameter
H is height
Substituting the known values,
V = (π(3m)²/4)(4m)/3
Simplifying,
V = 3π m³
The volume of the cone is equal to 3π or 9.42 m³. The value should complete the volume statement of the cone.
