Please help this is so confusing ;-; A cylindrical swimming pool has a diameter of 24 feet and a height of 4 feet. A smaller pool with the same height has a diameter of 12 feet. A vinyl liner covers the bottom and side of each pool.

a. Does the smaller pool require one-half of the amount of vinyl liner that is used to cover the larger pool? Explain. If not, estimate the diameter ns of the cylindrical swimming pool that uses one-half of the amount of vinyl liner used to cover the larger pool. Assume the height of the pool is 4 feet.

b. To install the vinyl liner, it costs $1.95 per square foot. You have $1000 in your budget to spend on the liner installation. What is the largest pool you can get without going over your liner budget? Assume the height of the pool is 4 feet.​
