Question

Find the radius of a sphere with volume 580mm^3, correct to 2 decimal places.

Answer 1

11.77

Explanation:

Volume of sphere =
`(4)/(3)` × π × r²

580 mm³ =
`(4)/(3)` × π × r²

( Divide both sides by
`(4)/(3)` )

435 mm³ = π × r²

( Divide both sides by π )

138.4648005 = r²

( Square root both sides )

11.76710672 = r
