Answer:
A
Step-by-step explanation:
Since the pyramids are similar, the scale factor will be 3. So the height of the small pyramid is 6.3/3=2.1. The volume will be (1/3)*(2.1)*(2.3)^2=3.70
Given that diameter of a paint can is 6.2483.
And we are asked to find width of four paint cans on a shelf.
Since we can only place paint cans adjacent to each other on a shelf, Total width will be addition of diameters of four paint cans.
Hence width = 6.2483+6.2483+6.2483+6.2483
= 24.9932 ≈ 24.99 inches( rounded off to nearest hundredth of an inch)
Hence correct option is 'A'.
Answer:
The volume of the cone is 
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
In this problem we have that
so
-----> equation A
The volume of a cone with the same radius and height is equal to
-----> equation B
Substitute equation A in equation B
X^2 + 14x + 17 = -96
x^2 + 14x + 113 = 0
x^2 + 14x + 49 + 64 = 0
(x + 7)^2 = -64
x + 7 = sqrt(-64) = + or - 8i
x = -7 + or - 8i
Answer:
Step-by-step explanation:
A standard die has 6 numbers, so the probability it will be greater than 4 is 6-4, or 2. Therefore the answer is 
, but this can be simplified to .
