Answer:
D. She used the beach's ball's diameter when she should have used the radius
Step-by-step explanation:
To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.
The formula she used is correct.
Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.
Radius (r) = ½(diameter) = ½(12) = 6 in.
This is where Emily made a mistake.
She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.
She should have gotten,
V = ⁴/3(3.14)(6)² = 904.32 cubic inches

Answer:
768 tiles would be required to tile the floor.
Step-by-step explanation:
Let's first calculate the number of square meters that the rectangular floor represents, by using the formula for the area of a rectangle (length x width):
Floor area = 8 m x 6 m = 48
Next, let's convert the side of the square tiles into meters in order to keep the same units in both (floor area an tile area):
25 cm = 0.25 m
Then the are of a square tile can be obtained by the formula 0.25 m x 0.25 m = 0.0625
Now to find the number of tiles needed, we perform the division of the total floor area to be covered divided by the area covered by a single tile:
Number of tiles needed: 48 / 0.0625 = 768 tiles
