Question

a 1/2 inch drill bit drills 10 holes in a one inch thick board. what is the volume of wood removed?

Answer 1

Answer:

=1.9625

Step-by-step explanation:

the drill bit would make a cylinder shape in the wood

volume of a cylinder:  3.14 x r^2 x h

V = 3.14 x .25^2 inch x 1 inch

V = 3.14 x .0625 x 1

V = 0.19625

There are 10 holes

10 x 0.19625

=1.9625
