Answer:
5) c. 6 pi cm
6) A. 81 pi mm^2
Step-by-step 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
A = pi 9^2
A = 81 pi mm^2
A. 81 pi mm^2
Circumference: 6πcm
Area: 81π mm^2
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
