Chapter 8 - Geometry - 8.6 Circles - 8.6 Exercises: 7

Answer

Circumference of the circle: 69.08 ft Area of the circle: 379.94 ft$^{2}$

Work Step by Step

Circumference of a Circle: $C$ = $2$$\pi$$r$ Therefore: $C$ = 2(3.14)(11 ft) $C$ = 69.08 ft Area of a Circle: $A$ = $\pi$$r$$^{2}$ Therefore: $A$ = (3.14)(11 ft)$^{2}$ $A$ = 379.94 ft$^{2}$
