Area of a circle equation:
A=(3.14)r^2

40(3.14)=(3.14)*r^2
40=r^2
r= square root of 40

simplified radius is 2 times root 10

Step-by-step explanation:

The volume of one such cylinder can be computed by multiplying the height by pi by the radius squared: 3×3.14×4²=150.72.

If you want to make 120 candles, multiply that number by 120: 150.72×120=18086.4.
