Hello,

I need help on this geometry problem.

1A) Chris's company makes solid balls out of scrap metal for various industrial uses. For one project, he must make copper balls that have a radius of6 in. If copper costs$0.75 perin^3,how much will the copper cost to make one ball? For your calculations, do not round any intermediate steps, and use the?

button on the calculator. Round your answer to the nearest cent.

2A) A company is going to make a storage container with sheet steel walls. The container will be in the shape of a rectangular prism, as shown below. If the sheet steel costs$40 for each square meter, how much will the sheet steel cost in total? H=5m W=2m L=4m

3A) A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is

25ft long and 20ft wide. If the gardener wants to build a fence around the garden, how many feet of fence are required? Do not round any intermediate computations. Round your final answer to the nearest hundredth and be sure to include the correct unit.
