Question

Mary wants to figure out how much space she has in her pencil holder. What is the volume, in cubic centimeters, of her pencil holder? Use 3.14 for TT

Formula: V = TTr2h

Answer 1

This is a cylinder so the formula would be πr²h.

V = (3.14)(4)²(9)
V = 452.16

The volume of the pencil holder is 452.16 cm³

Hope this helps :)
