Question

When using the Sphere Volume Formula
4/3 x Pie(3.14) x r^3
Can I turn 4/3 into 1.3?

Answer 1

yeah that is rite too...

Answer 2

Yes you can

Answer 3

also you can do like 4*pie*r^3 and divide it by 3....

Answer 4

So...

The radius of a sphere is 8 mm. Approximately what is the volume of the sphere?
A. 36π mm^3
B. 171π mm^3
C. 385π mm^3
D. 683π mm^3

I'm confused... I did both of those and got these..

1.3 x 3.14 x 512 = 2089.984

and

4 x 3.14 x 512 / 3 = 2143.57333333333...

Where did I go wrong? o_o

4/3 * pi * r^3. Dont take pi

Answer 11

1.3 x 512 = 682.66π @CrazyCountryGirl clear now...

Answer 12

also 4 x 512 / 3 =682 66π @CrazyCountryGirl
