what is the volume of a sphere with radius
r is given by the formula v=4/3 r^3
Find the volume of sphere with radius 4 meters. use 3.14 for the value of x and
round your answer to the nearest tenth.
4/3*4^3
85.3
your formula is incorrect , it should say
V = (4/3)π r^3
so if r = 4
V = (4/3)π(4^3)
= 256π/3 = appr. 267.9 m^3
To find the volume of a sphere with a given radius using the formula V = (4/3)πr³, you need to substitute the radius value into the formula and perform the necessary calculations.
In this case, the radius is given as 4 meters, and the value of π is given as 3.14.
Let's substitute these values into the formula:
V = (4/3) * 3.14 * 4^3
To calculate the volume, start by raising the radius to the power of 3: 4^3 = 4 * 4 * 4 = 64.
Now you can substitute the value of the radius into the formula:
V = (4/3) * 3.14 * 64
Next, perform the multiplication:
V = 267.946666...
Rounding to the nearest tenth, the volume of the sphere is approximately 267.9 cubic meters.
