Find the radius round your answer to the nearest tenth

r = 3m

Step-by-step explanation:

Formula for the volume of a sphere: V =

We want to find the radius so we use algebra to rearrange the equation to make the radius (r) the subject of the equation

Divide both sides by

=

Divide both sides by

=

Take the cube root of both sides

= r

Substitute V = 36 into the equation

r =

Expand the bracket

r =

Divide 108 by 4 (For this, the two in the numerator and denominator cancel each other out, and you only need to divide 108/4)

r =

The cube root of 27 is 3, because = 3 x 3 x 3 = 27

r = 3
