11. Max is designing a hot tub for a local spa.

Bezzdna [24]

Answer:

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)
