Responses
A V = 4(3.14)(4.5)3
V = 4(3.14) ( 4.5 ) 3
B V = 43
(3.14)(4.5)2
V = 4 3 (3.14) ( 4.5 ) 2
C V = 43
(3.14)(4.5)3

To find the volume of the given sphere, we can use the formula V = (4/3)(π)(r^3), where r is the radius. In this case, the radius is 4.5.
Substituting the values into the formula, we get V = (4/3)(3.14)(4.5^3)
Calculating this, we get V ≈ 381.5 cubic units
Therefore, the correct choice is C: 381.5 cubic units.
Substituting the values into the formula, we get V = (4/3)(3.14)(4.5^3)
Calculating this, we get V ≈ 381.5 cubic units
Therefore, the correct choice is C: 381.5 cubic units.
A soccer field is a rectangle 90 meters wide and 120 meters long. The soccer team ran from one corner to the other corner, along the diagonal of the soccer field.
How far, in meters, did the players run?
How far, in meters, did the players run?
To find the distance the players ran, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the width and length of the soccer field form the legs of a right triangle, and the diagonal represents the hypotenuse.
Using the Pythagorean theorem, we can calculate the length of the diagonal as follows:
diagonal^2 = width^2 + length^2
diagonal^2 = 90^2 + 120^2
diagonal^2 = 8100 + 14400
diagonal^2 = 22500
Taking the square root of both sides, we get:
diagonal ≈ √22500
diagonal ≈ 150 meters.
Therefore, the players ran approximately 150 meters.

diagonal^2 = width^2 + length^2
