Part A: What is the area, in square feet, of the rug
rounded to the nearest whole number?
Part B: What is the circumference, in feet, of the
rug rounded to the nearest whole number?

a = Th Formula for area
C=2111
Formula for finding circumference

Answer 1

A = 7

C = 9

Explanation:

A = (pi)r^2

diameter = 3
3/2 = 1.5
A = (pi)1.5^2
A = (pi)2.25
A = 7

C = 2(pi)r
diameter = 3
3/2 = 1.5
C = 3(pi)
C = 9
