Answer:
The total number of balls in the pyramid will be 55.
Step-by-step explanation:
Cannonballs are stacked In a pyramid shape with a base of 5 cannonballs on a side.
Therefore, at the base, the number of balls is 5².
In the layer above the base layer, there are 4 balls on each side.
So, in the layer above the base layer, the number of balls is 4².
Similarly, in the next levels, the number of balls will be 3², 2² and 1.
Therefore, the total number of balls in the pyramid will be (5² + 4² + 3² + 2² + 1) = 55. (Answer)
Question:
The options are
A. area
B. height
C. volume
D. perimeter
Answer:
The correct option is;
C. volume
Step-by-step explanation:
Here we note that the size of the unit cube is 1 cubic unit
When the box is filled with the unit cubes the total number of unit cubes represent the volume capacity of the box into which the number of nit cubes are placed.
The volume is a quantity that is also represented by the product of the length, width and height dimensions of the cube.

Answer: angle Q = 75 degrees</h3>
Explanation:
The order of ABC and RPQ is important so we can match up the angles like so
- angle A = angle R .... first letters
- angle B = angle P .... second letters
- angle C = angle Q ... third letters
Meaning that angle Q = 75 since angle C is this measure.
Answer:
(-4, -1/2)
Step-by-step explanation:
to calculate the midpoints bt of the line use the ormula:
Where (x1, x2) is one coordinate point and (y1, y2) is anither coordinate point. Any two points will work, but I chose A (-5,-4) and B (-3, 3).
(-4, -1/2)
Answer:
942 ft²
Step-by-step explanation:
The diagram shows the area to be 3/4 of that of a circle of radius 20 ft. The area of a circle is given by ...
A = πr² = π(20 ft)² = 400π ft²
Then 3/4 of that area is ...
dog run = (3/4)(400π ft²) = 300π ft² ≈ 942.48 ft²
The area of the dog's run is about 942 ft².
