Question

The volume of a sphere is given by the formula
V=4
3πr3
If the Volume of the sphere is 800cm3 calculate the radius, accurate to two decimal places.

Answer 1

I AM SO SORRY THE VOLUME OF A SPHERE IS
\[V = \frac{ 4 }{ 3 } \times \pi \times r^3\]

Answer 2

V is 800(Given)

Answer 3

\[800 = \frac{ 4 }{ 3 } \times \pi \times r^3\]

Answer 4

\[\frac{ 800 \times 3 }{ 4 } = \pi \times r^3\]
