Answer:
easy peasy
Step-by-step explanation:
we have, area = 497 sq. units
that is, (pi) (radius)^2=497
=> (22/7) x r^2 = 497
=> r^2 = 158.13
=> r = √158.13
=> r = 12.57
now we also have radius, soooo
=> circumference = 2 (pi) (radius)
=> (2) (22/7) (12.57)
=> 79.01 inches
Answer:
8.43 years
Step-by-step explanation:
Given data
Cost price P= $4995
Rate r= 10%
FInal amount A= $2150
The expression for the time/duration is given as
t= ln(A/p)/r
t= ln(2150/4995)/0.1
t= ln(0.430)/0.1
t= 0.843/0.1
t= 8.43
Hence the time it will take is 8.43 years
