Circumference = 43.96 m

Area = 153.86 sq.m

Step-by-step explanation:

here's the solution :-

circumference = 2 × pi × r

=》C = 2 × 3.14 × 7

=》C = 43.96 cm

circumference = 43.96 m

Area (A) = pi × r × r

=》A = 3.14 × 7 × 7

=》A = 153.86

Area = 153.86 sq.m

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
