Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm

Solve for x

Solve for y in 


So:

Ya
compound interest
A=P(1+r)^t
A=amount final
P=principal
r=rate in decimal
t=time in yers
so
interest is 9.5% or 0.095
principal is 10000
time is 3 years
A=10000(1+0.095)^3
A=10000(1.095)^3
A=13129.323
rounded
he owes $13129.32
