Answer 1

5) c. 6 pi cm

6) A. 81 pi mm^2

Explanation:

5) Circumference of a circle = pi d

d = 6 cm

so

C = 6 pi cm

Answer

c. 6 pi cm

6)

A = pi r^2

r = d/2 = 18/2 = 9

so

A = pi 9^2

A = 81 pi mm^2

Answer

A. 81 pi mm^2

Answer 2

Circumference: 6πcm

Area: 81π mm^2

Explanation:

1. C = πd

C = 3.14159 * 6

C = 18.84cm OR C = 6πcm

2. A=πr^2

A = 3.14159 * (9^2)

A = 254.46mm OR 81π mm^2
