A circular garden with a radius of 80 feet has a crosswalk that is a chord. The crosswalk is 14 feet from the center of the garden. To the nearest tenth of a foot, what is the length of the crosswalk?

Ineed on quadratic equations to solve problems

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
