Answer:
im pretty sure its 418. XD
Step-by-step explanation:
Problem 3
Circumference = pi*diameter
C = pi*d
C = 3.14*7.6
C = 23.864
C = 23.9
<h3>Answer: 23.9 cm</h3>
=======================================
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
<h3>Answer: 30.985 square cm</h3>
=======================================
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
<h3>Answer: 28.26 square millimeters</h3>
