Question

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

Answer 1

Answer:

We know,

$\:\sf{Volume\:of\:sphere\:=\:\frac{4}{3}πr³}$

Here,

Given :-

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

Solution :-

Now,

Volume of sphere = $\:\mathsf{\frac{4}{3}\:πr³}$

=> $\:\mathsf{\frac{4}{3}\:×\frac{22}{7}\:×(5)³}$

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!

Answer 2

Answer:

• b. 524 mm³

Step-by-step 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
