Question

The spherical head of a straight pin has a radius of 0.8 mm.



What is the approximate volume of the head of the straight pin? Use 3.14 to approximate pi and round your answer to two decimal places.

Answer 1

the formula for volume is V=(4/3)(pi)(r^3)
plug in 0.8 for r
3.14 for pi
and solve for V

Answer 2

I still don't get it

Answer 3

im sorry im a little slow today
\

Answer 4

\(V_{sphere} = \dfrac{4}{3} \pi r^3\)

\(V_{sphere} = \dfrac{4}{3} (3.14) (0.8)^3\)

Multiply 4/3 * 3.14 * 0.8 * 0.8 * 0.8
