Question

Find the volume of the spear. Give your answer to the nearest cubic unit. 5mm

Answer 1

• b. 524 mm³

Explanation:

Volume of the sphere

• V = 4/3πr³

Here, the radius (r) is 5 mm.

Solving

• V = 4/3 x 3.14 x 5³
• V = 4/3 x 3.14 x 125
• V = 4/3 x 392.5
• V = 524 mm³

Answer 2

We know,

`\:\sf{Volume\:of\:sphere\:=\:(4)/(3)πr³}`

Here,

Given :-

`\:\mathsf{radius\:=\:5mm}`

Solution :-

Now,

Volume of sphere =
`\:\mathsf{(4)/(3)\:πr³}`

=>
`\:\mathsf{(4)/(3)\:×(22)/(7)\:×(5)³}`

We got,

Volume of sphere = 523.809

Therefore you can say that option B. 524 mm³ is the correct answer for this question.

Hope this helps!
