Answer 1

Problem 3

Circumference = pi*diameter

C = pi*d

C = 3.14*7.6

C = 23.864

C = 23.9

Answer:  23.9 cm

=======================================

Problem 4

A = area of square

A = side*side

A = 8*8

A = 64 square cm

B = area of circle

B = pi*r^2

B = 3.14*(5.5)^2 .... radius = 5.5 is half of diameter = 11

B = 94.985

C = area of shaded region

C = B - A

C = 94.985 - 64

C = 30.985

Answer:  30.985 square cm

=======================================

Problem 5

diameter = 6

radius = 3

area = pi*radius^2

A = pi*r^2

A = pi*3^2

A = 9*pi

A = 9*3.14

A = 28.26

Answer:  28.26 square millimeters
