Find the volume of a sphere with a radius of 10 feet. Round to the nearest whole number.
A.) 1,257 ft³
B.) 4,187 ft³
C.) 1,089 ft³
D.) 1,568 ft³
B.) 4,187 ft³
(4/3) pi r^3
(4/3) * 3.14 * 1000
4,187
Yes B
impatient much?
Once is enough, thank you.

To find the volume of a sphere, you can use the formula V = (4/3)πr³, where V is the volume and r is the radius of the sphere.
In this case, the radius of the sphere is given as 10 feet. So, substitute r = 10 into the formula:
V = (4/3)π(10)³
Now, calculate the volume using the formula:
V = (4/3)π(1000)
= (4/3)(3.14)(1000)
= 4186.67 ft³ (rounded to 2 decimal places)
Since we need to round to the nearest whole number, the correct answer is:
A.) 1,257 ft³
Therefore, the answer is A.) 1,257 ft³.
