Answer:
The volume of a cylinder is given by the formula: V = πr^2h where r is the radius and h is the height. Substituting the given values, we get: V = π(4 in)^2(3 in) V = π(16 in^2)(3 in) V = 48π in^3 Therefore, the volume of wax needed to make one candle is 48π cubic inches. To find the amount of wax needed for 120 candles, we can multiply the volume of one candle by the number of candles: Amount of wax = 48π in^3/candle × 120 candles Amount of wax = 5760π in^3 So the company will need 5760π cubic inches of wax to make 120 candles.
