Answer:

<em>Circumference:</em> 18.84 cm

<em>Area:</em> 28.26 cm^2 (exponent 2)

Step-by-step explanation:

Circumference = 2(pi)r

The diameter is 6. Means the radius is 3 (half of 6)

pi = 3.14

2(3.14) x 3 = 18.84

Circumference is 18.84 cm.

Area of a circle = (pi)r^2

(3.14)(3)^2 = 28.26 cm^2 (exponent 2)
