I really need help with these questions to pass

Rewrite Literal Equations: Investigation 2 Susan makes and sells cylindrical wax candles. To make a candle, Susan buys a block of wax, melts it, and pours it into molds to make the candles. Susan usually prices a candle based on the volume of wax she uses to make it. Answer the following questions making sure to include appropriate units on your answers. 1. One of the molds makes a candle with a radius of 4 inches and a height of 1 foot. What are these lengths given to the nearest tenth of a centimeter? (1 inch = 2.54 centimeters) 2. A customer orders a candle with radius of 6 centimeters and height of 20 centimeters Use V = arch to calculate the amount of wax needed. Round to the nearest cubic centimeter. 3. A second customer orders a candle 10 centimeters tall and Susan uses a whole block wax. The volume of the wax is printed on the box. Which value is unknown? A. V B. C. r D. h 4. Rewrite the volume formula to solve for the radius of the candle. Then, use the new formula to find the radius of the candle made for the second customer if 2,450 cubic centimeters of wax are used. Round your answer to the nearest tenth of a centimeter. The measure of the radius is 5. A third customer asks Susan to make his candle so that the diameter and height are the same length. Rewrite the volume formula to solve for the radius. Explain why the radius depends only on the volume of wax used and no other variable
