Find the volume of a sphere with a radius of 3 m. Use 3.14 as an approximation for pi. Round your answer to the nearest hundredth, if necessary.(1 point)
The volume is
m3.
The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere.
Using the given radius of 3 m and approximating π as 3.14, we can substitute these values into the formula:
V = (4/3) * 3.14 * 3^3
= (4/3) * 3.14 * 27
= 113.04 m^3
Rounding to the nearest hundredth, the volume of the sphere is 113.04 m^3.
Find the volume of a sphere with a radius of 9 cm. Leave your answer in terms of pi.(1 point)
The volume is
cm3.
The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere.
Using the given radius of 9 cm, we can substitute this value into the formula:
V = (4/3)π * 9^3
= (4/3)π * 729
= 3056π cm^3
Therefore, the volume of the sphere is 3056π cm^3.
To find the volume of a sphere, you can use the formula V = (4/3) * π * r^3, where V is the volume, π (pi) is approximately 3.14, and r is the radius.
In this case, the radius is given as 3 m.
Plugging the values into the formula, we have:
V = (4/3) * 3.14 * 3^3
V = (4/3) * 3.14 * 27
V = 113.04 m^3 (rounded to the nearest hundredth)
Therefore, the volume of the sphere with a radius of 3 m is approximately 113.04 m^3.
