1. Problem Description

The problem states that a company makes spherical wax candles. Each candle has a diameter of 18 cm. The company has a total of 76,302 cm3cm^3 of wax. We need to determine how many candles can be made, using π=3.14\pi = 3.14.

2. Solution Steps

First, we need to find the volume of a single candle. Since the candle is a sphere, we use the formula for the volume of a sphere:
V=43πr3V = \frac{4}{3}\pi r^3
where VV is the volume and rr is the radius. The diameter is 18 cm, so the radius is half of that, or 9 cm. We are told to use π=3.14\pi = 3.14.
V=43(3.14)(93)=43(3.14)(729)=4(3.14)(243)=12.56(243)=3052.08cm3V = \frac{4}{3} (3.14) (9^3) = \frac{4}{3} (3.14) (729) = 4(3.14)(243) = 12.56(243) = 3052.08 \, cm^3
Next, we divide the total volume of wax by the volume of a single candle to find how many candles can be made.
Number of candles =763023052.08=25= \frac{76302}{3052.08} = 25

3. Final Answer

25 candles
